I’m looking for a member post to group blog solution.

We have 8 groups with 8 group blogs.
I would like group members to post directly to the group blogs from the group page with simple fields for text, link, image, video.

My first thought is to make a posting form on each group page that posts to the group blog with an approval process for admin.

Is there a buddypress plugin for this or could this be added to BuddyPress Activity Plus?

Thank you
