Ebtax Defaulting Order for R12 (Payables)

Dear Community,

 

Running R12 ... Ebtax, It seems that the tax classification code has been removed at the Invoice Header level in the Invoice Workbench.  In the tax defaulting screen in ebtax setup it still mentions you can default the tax classification code at the invoice level.  I cannot find a setup to do this though.  I see Operating Unit level, Supplier, Supplier Site but how do I set the tax classification code default at invoice level now.  Is this gone in R12?
