Is there a way to default a "Do Not Bill" expense entry when it originated in QuickBooks?

Entering a check in QuickBooks and importing into Timeslips premium as an Expense using Create Slips from QuickBooks is not defaulting the new entry as "Do Not Bill" even though the expense code is setup properly. When i use the same code and enter an expense directly into Timeslips it defaults to do not bill. Is there a way to default a "Do Not Bill" expense entry when it originated in QuickBooks?
