SDK Application: Launch SL screen, pass parameter, then Finish

I am creating a new SDK application that will display all SL Shippers at the Confirm Shipment step, and want to perform a mass update of those Shippers (rather than individually confirming each one). I have most of the code worked out, but am missing how to get the 40.117.00 screen to perform the "Finish" command once the ShipperID has been populated.  The CallApplicWait command will open the screen, but what do I need to do in order for the Shipper screen to call the Edit_Finish command and process the Shipper?

Also, can I call the 40.117.00 screen without displaying it (visible=false)?

Call ApplSetParmValue(PRMSECTION_VBRDT, "ShipperID", bConfirmShippers.ShipperID)

Call CallApplicWait("4011700", "")
