As far as I know, there isn’t such a plugin for BP, however there are some for MU.

Did a quick Google search; here’s two promising solutions:

1) https://mu.wordpress.org/forums/topic/1659

2) http://plugins.paidtoblog.com/wpmu-power-tools/

Just wanted to reiterate that none of these take care of BP though… so you might want to keep this under consideration.
