Stop Prepaid Voucher from Applying

Goal:

Create a prepaid voucher, pay it but not have it apply to regular vouchers immediately.

Reason:

Sometimes we create a prepay but do not want it to apply to invoices for several months. Is there a way to temporarily stop the prepays from applying? Our system is setup to automatically apply prepayments and this works for 90% of our processes so we would not want to change and apply manually
