Mark individual seasons as Planning

Not sure if this is already possible, I can’t find how if so.

But there are a few Seasons of shows I would like to mark as “planning” to watch, but I don’t see how to add individual seasons.

Like, if I watched season 1-3 of a show years ago but missed seasons 4-7, I’d like to add those missed seasons to my “planning” list instead of adding the entire show.

Same with anthology shows which are different/self contained each season, where I just want to watch some seasons but not all of them (example: American Horror Story).

There’s a few other reasons to mark individual seasons as Planning too, but you get the idea.

At the moment I have individual seasons on a personal list, but would it would be cool to have all the planned watches of seasons, on the planned list.
