as I know that shopify don’t have an available feature to have a multi coupon feature in Shopify, standard feature. we need to look for the process and possible features to be applied.
-The staff should be able to fill in the store code in the discount code apply field at the checkout page. So we need to ensure that we should be able to have a multi coupon apply feature.
-Able to generate the unique code with a specific prefix (to identify the store location or even staff) with the expiring lead time within 30 mins.
all the concept in above if anyone has as ideae or have a app plunig that fit with my requirement
please kindly share
