Warranty / CP Split payment on Warranty Line

It would be great if there can be an option for the customer pay portion of a work order to be added directly through the warranty line as appose to adding a second labour line for this payment. Currently, in the event that the RO is closed for any reason and the payments are still pending this requires the posting to be relocated to a different account after the fact as appose to automatically allocating right off the bat. It also sets it to labour default which also effects the back end sales results for month end. This option would simplify the transaction for the advisor and the client and will also simplyfy it on the back end for accounting. Thank you.
