This idea applies to both Customer Payment Proposals and Vendor Payment Proposals. We are creating very large payment journals of several 100 payments. Most of the time we want the payment method on the invoices to carry over to the payment, however there are occasions where we need to override the payment method. When dealing with very large journals, this can be tedious. The payment can be updated on the proposal preview screen using the update multiple rows option, but then you can't use the extremely handy batch mode which will multi-thread proposal.

Method of Payment should be added to the Advanced parameters Fasttab of the proposal screen so that it can override the Method of Payment in the same way that the offset account type and account works now.
