Full cast per season of a TV show

Hey!

I would love to be able to see full cast based on seasons. The ability to at least show the cast of just one season would be great. If you could simply add and remove seasons and then show the cast based on selected seasons it would be cool. 

You could for instance add something like this to the full cast pages of TV shows. Then you could simply click the seasons you're interested in seeing the cast and crew for, and then only the relevant cast/crew will show up. 

It would also be nice if you could add which seasons the cast worked on, not just the episodes & years.
