Siosa in Library

I canot believe this hasnt been asked for before, or even in game already

But, why cant Siosa in act 3 use currency in our tabs just like we can from other vendors, its a PITA to have to keep porting from town to the library with the right currencies - especially when your poor and dont just take a load

TL;DR

Give Siosa in the library aiblity to use currency directly from our tabs for shopping gems :)

+1. I'm sure it has been asked for. I don't see any benefit to him not having it. Maybe there is a technical reason with him not being in town, but it is not fun, particularly if you don't know the prices of the gems.
