Feature Request - Pro Sites Site Admin Bulk Extend

Hi

If I activate Pro Sites all my MU blogs have the 'please pay the bill mofo' error.

I then had to activate and then manually extend every blog from the network admin 'sites' page.

Is it possible to create an option to tick all the sites I want to extend, then hit the drop down to extend.

That list of site ids is then passed to the next page where I select level and date/permanent.

This also minimises the down time of the mu blogs.

Cheers

Johnny
