Is it possible to make BOM balloons that point to a different item?

So here is what I have going on. I am making hydraulic hoses (without the piping extension... long story) but anyways here is what I am doing.

1. I create and model x_hose_rep.

2. I then insert that model assembly x.

3. I include one hose part number y (Our company has bulk (not set up as bulk in creo, but bulk in reality) hose set up as a 1 foot section in creo. )

4. I create the drawing and BOM, there is the fitting, the one section of hose y, and one x_hose_rep.

5. I filter out the x_hose_rep using repeat regions

6. I create relations to modify the qty in the bom to make the hose y match what we really need.

That means that the hose in the picture of the part, is not actually the part that is shown on the BOM, so making BOM balloons becomes tougher.

Now that you understand what I am doing (right or wrong, doens't matter), Is there a way to point a balloon to the the x_hose_rep part and have the number on the balloon relate to the y part number (the bulk hose).

I know that I can manually type in a number on a balloon, is there a way to relate that manual balloon with the part number y so that the BOM will change if the list number changes for some reason?

This might be helpful for other situations as well.

Thanks in advance
