Cubepoints on Multisite?

I installed Cubepoints network wide for my whole (Buddypress) Community with Multisite Support, as every of my Members can have an own blog!

I was very happy with it and my members also until I found out, that every Blogowner gets not only points for their Blogs and animated by this way to have a busy Blog, but that they are also able to manage the Points of every person in the Community.

Has any one an idea how it can be possible in cubepoints to honor the members writing Blogentries without giving them the chance to manage the cubepoints for the whole multisite network? I – as Superadmin – only wants to have the right to manage the points on the main site.

Has anyone here already a solution for this problem or ideas?
