Currently on Invoice complete, Authorization is captured if invoice amt match. There are some case where Bank do not allow to void authorization.
In such case it is good to allow to do partial capture of authorization without attempting to void existing authorization.
We can add flag on payment processor, IsPartialCapture (Partial Capture), if this flag is true and capture amt is less than authorization amt then should perform partial capture. Also should add field for CapturedAmt on payment trx to keep track of amt captured/authorization.
