Is there a way to use balloons to call out the subassembly part number instead of the individual component inside the sub assembly? 

Example 

I have an electrical enclosure that has subassembly LC2D09BD in it, it displays that part number in my bill of material correctly. But when I use a balloon on my drawing, showing the "part number(BOM)", it is showing "PRUDUCT_ID_117" instead of the part number in the BOM.
