I think this would come in handy particularly for shows that seem to bounce around in syndication.

It would be nice

This is the only one I know of--it details all the shows CBS Program Dist. controls.

Speaking of syndicated shows, here's a little tidbit that I can't seem to figure out. A hit series normally should be able to hit syndication after 4 seasons or 100 episodes (or 88 in the modern era). Yet while I was looking at my online TV guide recently, I noticed that the ABC sitcom Speechless, which is just wrapping up only its 2nd season and has only aired 40 episodes so far, is already running 5 days a week on the Canadian Family Channel at 8:30 pm. That doesn't make sense to me yet it's a tremendous bonus for Canadian fans of the series. I wouldn't be surprised if the same thing happens next season with Young Sheldon. I can handle watching it every day. :)

I found a list of the major syndication companies on the Ranker website and the shows they carry on Wikipedia and their various homepages. Here's the list of sitcoms carried by each one that I've been able to find:
