Adding functionatlity to create/edit vouchers and their codes would be useful for a number of use cases.

Firstly in my opinion the Mews process for creating this is a little clunky, especially if you want to track the usage of each VC as it needs to be it's own Voucher, there's no way to track the codes within that voucher.

Therefore lets say you have a staff friends & family rate, and you want the voucher code to be the employee name so you can track usage and abuse of the incentive.

Creating additional codes for an already created voucher is one thing but as I said above you can't track individual codes. For this reason you need to create a new voucher. Now imagine you want this code to work across all your properties and you have a large portfolio, you have to create the voucher/code within each property. Lets say you have 100 employees across 10 properties (arbitrary numbers) this means the creation of a total of 1,000 vouchers in total, in order to be able to track them. Now amplify that to 1000 employees across 50 businesses... For each new employee, for their unique code to work you'd need to create 50 vouchers, one for each property.

Doing this via an integration would be so much quicker.

Other use cases are marketing campaigns where you want a unique voucher per campaign to track the ROI of each.
