PCID as reference only

I wonder if I can use PCID as a reference only, means that for inventory transaction I do not need to input the PCID number. Is it possible to do this?

I produce bolts, and I use containers in shop floor, I use flow tag for inventory transaction, but I still need to put the containers number when I receipt from job operation as a reference only so when the material handler should move the part he knows the container number from the system and can easily to search in the shop floor.
