Featured Content per Group (Sticky per group)

I'm not sure how many other people might have this problem, but I was wondering if there was some way to make a post sticky for just a particular group?

Use case: I am organizing a regional event that I would like to cross post to other nearby groups who may be interested, and make featured/sticky on the local groups homepage. However, if the post is marked sticky then it becomes sticky for all groups and seems rude, at the very least, if not abuse to impose the importance of one group on the other groups.

I can see this being a general feature request for other people who use OG for other sites as well, so maybe there is an existing solution for this.
