Hi guys, I currently have 2 product groups, group A which allows PayPal and Bitcoin as the payment method and product group B which allows Bitcoin only. I would like to make an exception for a product inside group B and allow PayPal as well. I have been searching for any built in solution for WHMCS but I havent find anything. Unfortunately, I can move the product to the other group because the product doesnt fit into the other category. Any advise on how to do this? Thanks in advance!
