Yes, we do have that on our backlog.
 
Specifically, what we have contemplated is to allow you to set a "tag" in the feed.  So for example, when you set up a new feed there would be an additional text box in the feed setup.  In that text box you could set one (or more) tags.  You could mark "twitter" for your twitter feeds.  You could also use this tagging for other groupings. 
 
When the SC's show up in the CR results they would already be tagged "Twitter" or other. 
 
The benifit of using (re-using) the tagging functionalty for this is that we plan reporting metrics based on tags, so if we use tags for this purpose you will ultimately be able to produce reports showing you volume and other metrics which would be pretty helpful for your use case.
