Identify Capital Creditors invoices

Hello,

As standard JDE, we are storing a specific GL offset in the supplier Master. Using the related AAI, we then book the Accounts Payable record of that supplier to a specific GL accounts.

Now, we also want to separate as to whether an invoice is a fixed asset or not. 

However we cannot simply change the supplier GL offset in the supplier Master, as a supplier can supply both Capital and expensed items.

Therefore, the user will need to overwrite the GL offset on invoice entry.

Do you know if there is any other way we can achieve this, or any other field that can be used for this? without relying on the user to correctly updating the GL Offset.
