Renumbering item #'s in BOM

Good morning all,

I have a BOM that is correct and parametric at this point.  There are some entries that are there that are from a "split body" feature.  They are also correct.  But I want to delete that row in the BOM and have my BOM item numbers update and have my balloons follow?  For example.  I have 1 -4 in the BOM and all balloons match correctly.  I remove row three and which is item 3 obviously and then I want 4 now to become three and have my balloons follow.

Any way to accomplish this?

Thanks

Sid
