Reality vs. IMDb contribution rules, Series vs. Episodes

Hi,
I see a problem with the classic "please only add credits to episodes" rule.
First of all we end up having a lot of false credits on imdb, because crew members want their credit listed asap and don't have time to become an "imdb contribution expert".
So if you get rejected a couple of times for trying to get the deserved series level credit, for a show you have worked on from first meeting to end, than people go the path of least resistance.
And this is deff not listing all missing episodes, as most of the time thats not even possible as no names/numbers known yet...
Reality is that most crew members than put their credit just in any episode that is listed as they simply don't know the episode title or numbers.

This leads to the fact that especially daily performers or daily crew (and imdb newbies of course) end up in the complete wrong episodes! Seen this a million times! Every one is just listed in that one episode which is first listed.
(Just think about that guy who got called in on a TV show as a daily performer, no infos, stand there, do this, It's a time loop scene which is the end of episode 9 but gets repeated in the beginning of episode 10 and, here it comes, the editor might decide to put it in several episodes... this guy is happy to be called in at all so not in position to ask many questions, wants to be low "maintenance" -How the hell is this guy supposed to put himself in the right episodes? Its unrealistic as a lot of the dailys barely know the name of the TV show they are working for, especially the busy ones)
   
No one wants to do "research" and start contributing all missing episodes! If you work on a new tv show you almost never know names for numbers of episodes because this is just not how crew works on set. While you work on the show its more about: this needs to happen that date! No one gives a *** what number or name that episode has also because empirically you don't need that information to do most of the jobs on a filmset. If there are numbers they also keep changing them and if you are daily crew you are simply not in the position to even ask about ANY detail of that project.
I know a lot of HOD's which don't give a call sheet to daily crew so they don't have access to contacts. The NEED TO KNOW system.

So the only way to ad my series level credit as general HOD for the hole series is to add all episodes!? For which I might have to call the executives or even the writer himself for?? -"Hi, can we please go together through all current numbers and names of the episodes as I need this to put my credit on IMDB and I don't want to contribute anything wrong..?" might come across weird don't you think?
And than on the other hand, if there is currently only one episode listed, putting in my credit only in one episode on a show I have worked continuously is kind of frustrating...
This " (1 episode) " label behind your credit is degrading for someone who has worked hard on every episode from beginning to the end.
Any help or trick out there to feel credited for series level work as HOD if there is only one episode listed and I don't want to be always the guy filling in ALL the gaps?
