Most definitely. I’ll check this later, but I need the attributes of the two (the post and corresponding group) to be very closely linked.

This may be something slightly above my station, though I’m definitely willing to give it a go. If it comes to it, I could write a massive SQL statement to shove the details in to BP on the new post query, but that would break any future WP upgrades.

Will report back for sure.
