Transfer AP DFF to GL using Subledger Accounting?

We are currently in 11.5.10 but starting an R12 upgrade project.

In 11.5.10, we had to build a 'custom' program to transfer DFF values populated on AP invoice distribution lines to GL during the 'Payables Transfer to GL' process.  Basically, if an invoice distribution line had a soecific DFF populated, we transferred the distribution line + the DFF to GL, where the same DFF was also enabled.

Ideally, we would like to transfer the AP DFF to GL using 'standard' functionality.  Does anyone know if this is possible using SLA?  If so, are there any White Papers that might explain the approach?

Thanks in advance!
