Is there any way to use the BOI on modules not created directly by Sage?

SOLVED

The example I'm looking at right now is MAPADOC. It seems that the table I need to update (EC_PSCase) does have a file in their folder named EC_PSCase_bus.pvc, and the EC module can be loaded successfully in VBScript. Is there a way to extrapolate the needed variable / function names to interact with this table using the BOI? We're looking to update the tracking numbers in the picking sheet from a file, but the table where that is stored is not available from the VI Import Job dialog.
