Multiple subcontract operations that get drop-shipped from one supplier to another

I’m working with a client that has a method where two (or more) subcontract operations are done back to back; after the first one is finished the supplier performing that operation drop-ships the parts to the second supplier. I’m trying to figure out how this can be handled in Kinetic so that the parts are visible on whichever operation they are on (IE. how many are on the first subcontract operation and how many on the second as well as when did the parts “move” from one to the other.)

Does anyone know how to do this that can give me some guidance? I would greatly appreciate the help!
