We use vouchers for gift cards and store credits. Is there a way that management can change the value set for a voucher? For example, if I just wanted to promo a few gift cards at certain prices with out making a sale for them, or if I wanted to adjust someone's credit with out them having to be here with the card? (If there was a mistake made by the cashier, and the value of the voucher was incorrect, can I adjust it from the back end some how?)
thanks in advance
