Any way to not use AutoAccounting when doing Manual Transactions? (i.e. Credit Memo)

We would like to use AutoAccounting when we run the AutoInvoice Master Program, that way it uses the "Standard Lines" as the table. However, when we do a Credit Memo there is no GL account that populates if we are crediting a non-inventory or sale able item. In this case we would like to use transaction type.

So if I were to credit let's say Tax, when I hit Distributions button, no GL account comes up because it is using AutoAccounting which for the natural segment is set to Standard Line. Any suggestions?
