Sort watch list by TV program name (not episode title)

It is possible to sort the watch list by various properties, such as Popularity or Rating. There is an alphabetical sort option but as far as I can see that one uses the TV episode title, as in the TV program Elementary episode Hounded will be sorted under H, not E.

I would prefer to sort by program name, since I rarely know what the episode title is but I want to be able to quickly locate a program in my list.

Am I missing something? If not, would it be possible to add an option to sort by program name as well as the current episode title?
