Nope. The store isn't very flexible. Item, cost and quantity only.

while im here :P
how would this work in a cluster? for example 1server running genesis, another running a mod map like Tunguska ? :)

could the point merge or transfer between servers?

This is the actual Hexagon shop. It isn't a custom one, it's the vanilla one just with the ability to customize the store.

Any points you have are on your character. If you transfer your character, they go with it.

awesome :)
