Corrections to existing series credits that should have had episodic credits

On many occasions I've tried to correct a credit that is in the wrong department by deleting the current credit and creating a new identical credit in the proper department, and it usually works fine. It doesn't work, however, when the original wrong credit has been grandfathered in so that it currently exists as an incorrect series credit that never got attached to an individual episode. 99% of the time I have absolutely no idea of which episode(s), if any exist at all, that the credit would belong to and the software won't allow the shifting of the credit, even though it is existing and a 'new' credit is not being added. If you try to add a date in the attribute field and click the various "Warning understood, go ahead anyway" boxes, you can go through about three of these steps and you are finally stopped for good. (I can show you these steps if needed).

So, we are left with no way to correct these grandfathered wrong credits. I would suggest, if possible, that along with the various warnings, a checkbox is included with something like:  If this is merely a correction or a move from one department to another, click here. This would then bypass the existing blocks and allow the existing grandfathered data to be corrected/transferred.
