Ability to enter discount amount against individual supplier payments when using suggested payments.

When building up the payments file in purchase ledger supplier payments they would like to be able to enter a discount amount against each invoice payment line.

They cannot currently do this as Sage 200 does not allow it if there has been no discount element entered on the original purchase invoice entry, however, their previous system (Interprise) does allow this functionality and they would like the same in Sage 200.
