Feature Request - All Watched All Episodes

Hi,

I know this might be late for request, not critical to add, just thought maybe a good feature to add.

I usually have my Episodes section set to Collapse All, to save some space and avoid scrolling too much to find the show I want.  And since I usually watch few episodes at a time, I come back to mark many episodes as watched.

Currently there is the "Mark X eps Watched - Acquired - Ignored" option per season, is there a way to add at least a "Marx All Episodes Watched" for whole series and have it nex to the Show Name and Tags? 

Here is capture screen I took with highlight in red where I see there is alot of area that can be used.  I know for many tags, this area gets crowded at times, so my suggestion is next to the Series Name to make it simple.  Not bothered if Aquired and Ignored is added for entire show, might also be a good addition to manage the whole show instead per season.

Here is link to capture screen  https://ibb.co/xqw9JKPh
