Pro Site Premium Plugin Pre Activation

Hi,

Hope you are doing well.

I am using pro site plugin feature for allowing access to certain plugin to pro users.

I have made certain changes in the premium plugins tab section were i have pre activated plugin which are available for use for free. But this changes will not activate free plugins on all the blogs previously created. It is getting activated on new blogs only.

So my question is, is it possible to auto activate free plugins to the blog created previously before i made the changes.

Thanks & Regards,
Suresh Patel
