Handling refunds to discount code with different currencies

Hello,

I can’t seem to find a way to create a discount code for a specific currency, only the base one.

The issue is, if we refund a customer order in a secondary currency to a store credit. E.G $100. If we create a discount code of 100, it uses the base currency. If we try generate it using a converted $100 into the base currency, it’s ofen miscalculated due to the time taken by the customer to redeem and the currency changes.

How can we issue discount codes in a set currency and value?
