How to disable budgetary controls against payables only

Hello,

We are using Projects as a way of maintaining CapEx requests and have been advised that if we enable budgetary controls it will give users a prompt if they exceed the amount when raising a requisition if they specify the project.

However when we enabled the controls, we now have the budget dates come up on the Payables workbench when entering an invoice which we don't want. I've seen in the configuration settings you can disable some specific settings against payables but it doesn't seem to be possible to just disable it against invoices, can it be done?
