Leaders showing both subassy and component properties

Let me start by saying I know I can't have something bothways, most of the time. Let me also say I have a drawing balloonleader that shows Part No and Description pulled from a customproperty combining the two.

Here's my problem.

I have a main assembly consisting of two sub assemblies. Pleasesee the two attached pics.

1. One of those sub assemblies is soldered together and should beshown as the 014-015 sub assembly number on the drawing. This subassembly consists of part 014-013 (body) and 022-011 (barb), butbecomes 014-015 sub assy.

2. The other sub assembly is an o-ring and a stem. I still needthis shown as a sub assembly, but want the leaders to showindividual part numbers.

I know about the configuration property setting "Don't show childcomps in BOM when used as a sub assy." AM I JUST OUT OF LUCK HERE?
