I have an odd question. I am transitioning my customers from an old payment system to Pabbly. Some of them already have some purchase history that was made through our old system. We'd like to retire this system which means that they will no longer be able to see their past purchases. Is there any way within Pabbly to manually add something that would represent past purchase history that the customer can see through the customer portal? I'm trying to do this without creating an item and then just marking it as paid since this adds income to the dashboard.
