Update to Payables Distributions after Transfer

In R12, Payables distribution lines are no longer updated when a supplier invoice transaction is moved from one project/task to aonther.

My client really wants to have that functionality.  If the the transfer results in a new account string being created, they want to see it in AP.

I realize the "transfer" could originate in AP but that poses problems:

1.  It takes longer to make the changes in AP.

2.  They don't want to give the Projects folks access to AP and Projects folks don't want to wait for AP to make their changes for them.

Any ideas?

Thanks
