Groups in library fields

Hi,

I’d like to be able to know what groups an article is in when looking at it. This would mean being able to list them in thelist of  library view opetions, like Author, last updated, etc.

Right clicking on a record and choosing “record summary” will list the groups a record is in.  You can click on the group to see who is in it.  Since an article can be in many groups, I am not sure how one would sort on the library via group?  That would mean the article would have to appear multiple times in the library display.
