Payroll costing - forcing an offset account segment to be blank

Summary:

Project code segment is populated on the cost account but we need it to be blank on the offset account

Content (please ensure you mask any confidential information):

Project code is a segment that is populated at position level. This feeds down to the cost account segment in eligibility costing and works fine.

But we need the project code segment on the offset account to always be blank. The default system behaviour is that if you don't populate a segment in the offset account then the cost account value is used. In this scenario, we do not want that, we want to force the offset segment to be blank.
