collaborations suggestion

I like to search for actors who have been in two TV and movie franchises. FOr example I have just been looking for actors who have been in both Star Trek and Doctor Who. It would make it much easier to d this if the collaborations feature were enhanced so I could create two lists of titles, then search for people who were in at least one title for list A and one from list B. If this is not possible, could it be made so that I can make a Collaborations search, then go back and amend the search by changing one of the titles, and resubmit.

I like the idea of this kind of search. But it's well beyond the current Advanced Search abilities so far as I know. I suggest this post be converted into an Idea. Meanwhile, I submitted "actors appearing in dr who and in star trek" to google, and it found this IMDb list (prepared by a user): https://m.imdb.com/list/ls052725708/ and this https://memory-alpha.fandom.com/wiki/Doctor_Who and much more.
