Is it possible to update project expenditure type for the early payment discount?

Summary:

GAAP accounting requires early payment discounts be booked to a contra-expense account but we have common options set to multiple lines to enable creation of project cost lines. We can override the allocation method for the natural account by creating an account rule through SLA. We believe, to be consistent with that, we should also map to a specific expenditure type for projects. There is also a reconciliation issue when we map the discount to a specific natural account but not to a specific expenditure type.
