What I need is for the "-1000" to also be variable. I need the first refund to be GS-order_number-1000, the second GS-order_number-1001, the third GS-order_number-1002, and so on. I am not sure how I can manage to make the "-1000" dynamic. Any ideas? I got in touch with the Shopify Theme and they told me that there is no easy solution for this. They suggested using a different app or getting in contact with an expert. Before I do this I would really like to receive your help if possible. Thank you so much in advance!
