Editing Voucher Balances

[tirnanog]

Hello, 

i use the square online vouchers, they are mostly used for services at my business however the service providers are actually self employed and we just handle the bookings and vouchers, as such it would be handy to be able to edit the balance of vouchers because some clients only use part of their voucher, however recording this as a sale in order to reduce the balance by the amount the service costs (by putting it through the POS) adds it on to our shops reports (which is a seperate business that does not have anything to do with the services provided) as such it can get confusing for our reports 

Long story short i would like to see the ability to edit the gift voucher balance rather than just clearing the entire thing
