Part payments through the Portal

When parents pay their fees via credit card through the portal it only lets them pay their account in full. It would be great if they could have the option to choose how much they want to pay.

In NSW Australia we have rebate vouchers parents are entitled to claim on their children's activities so often they need to pay $100 less than the actual total on their account so they can't pay through the portal until the rebate has been applied. it would be great if they could choose what amount they pay so that they can take the $100 off and pay before we apply the rebate rather than having to wait. Some of our parents also like to pay themselves by instalments so this option would allow them to pay through the portal in smaller increments.
