Use lists for the feed

Now that we have lists of stared repositories I want to be able to specify one (or more??) lists that should be used for my feed.

I frequently use stars as bookmarks to remember a repository that I might be interested in later. That doesn't mean that want to receive day to day updated about them. By being able to set list(s) that I want to be used for my feed I can manage which repositories are shown in them.
