How to Pass Parameter Column in AP Invoice like Supplier ID to DFF

We are currently on Oracle Fusion Payables Cloud Service. We have a requirement where, for a DFF field on the invoice header, we need to derive a value from the supplier master for the vendor/supplier value selected/provided by the user on the invoice. In R12 EBS, this was possible using blind variables. Want to understand whether this is possible in Fusion AP. Thanks in advance for any help or ideas provided.
