Item skins in "cost" tab in Vending Machine

Would it be possible to also change the looks for items inside a vending machine? At the moment, the reskinned item doesn't show up in the "cost" tab, presumably because it doesn't (yet) exist. As soon as the transfer is made, the items in the player's and VM's inventory are properly skinned. 

the "for sale" tab works as intended, as the item for sale exists in the inventory of the VM.

 

If its not working then i am like 90% sure its on client-side, so it can't be modified or edited...
