Trying to load burden expenditure type classes via FBDI but see not finding template that allows

Summary:

Trying to load Expenditure types with "Burden" expenditure type class, already "accounted in 3rd party application" via FBDI template but Trx Source not allowed in Unprocessed Labor FBDI.

Content (please ensure you mask any confidential information):

I was hoping to load in same FBDI template along with the Straight time exp types that the burden expenditure type is calculates against as a separate exp type in the source application. Also and not seeing another FBDI for Burden exp type classes. IT seems it can be done in ADFI but prefer FBDI

Any advice or best practice:

1. Loading Straight labor that is accounted in 3rd party application with raw and also burdened costs for capital projects via FBDI
