Predefined Payment Types in OM.

Oracle Release 12.2.8.

In OM we see that there are only 6 available payment types that can be linked one to one to the receipt payment methods in AR.

But for example, for payment type CASH we have three cash equivalent receipt methods, such as Cash, Cashier's Check, and Money Order.

So what is the recommended way to link one payment type to the multiple receipt methods? Or can this only be achieved via a custom approach and some sort of a user defined lookup table? The current payment type list is not expandable in OM.

Looking for some suggestions and perhaps previous experience.
