Update Center issue: How to hide/remove items from the Available Plugins tab

Hello!

I have a Netbeans 8.0.1 platform suite/application App1 that has its own update center.  I have another platform application App2 with its own modules that uses App1 as a library, but some of the modules from App1 are disabled.  App2 also has its own separate update center.

The problem is that when I goto Tools->Plugins in App2, under the "Available Plugins" tab, it shows the modules that I have disabled in App1 as available for install.  This is undesirable, since one of the reasons I created App2 is because I do not want the users to have access to those disabled App1 modules.

Is there some way to prevent those disabled App1 modules from showing up in the "Available Plugins" tab?

Thanks!
