Can we make the DFF autopopulated based on chosen Expense Type?

Summary:

We have added a DFF in Expense type just for the SLA accounting rules when the Expense imported to AP, expense distribution only comes from Expense Type = Natural Account and Expense Default account in Employee. Our client needs to have a specific combination per Expense Type, and we can only do that using a DFF from expense and carry over to AP Invoice Line Interface Line values - and from there we have Mapping set for the SLA rules.

Is there a way to automatically copy the selected Expense Type to the DFF value?
