XF 1.3 User upgrade permissions?

[SpecialK]

We need to be able to set some user upgrades to only be purchasable by users in certain usergroups.

For example:

Group A can only purchase upgrade A
Group B can only purchase upgrade B
Everyone can purchase upgrade C
Group C can only purchase upgrade D

Etc..

I cannot figure out a way to do this in XF. We use this feature extensively in VB and really need it in XF.

Is this possible either stock or via an addon?

That is not possible in the default software.
It would require custom development.
