EAP 9.2 - Approval Required to Manually Apply Prepayment

Hello,

We have a question regarding manual application of a voucher to a prepayment. For example, we create a Prepaid voucher for $1,000. Later we create a regular voucher for $5,000 and wish to apply just $500 of the Prepaid voucher to it. When we attempt to do the application, the regular voucher has to be Approved before it is available to use.

Problem is, that means that we have to get the voucher approved for the $5,000, even though the payment will only be $4,500 after the prepayment is applied.

Is there some configuration where we can "turn off" this requirement? We would like to do the application prior to workflow approval.
