Is it possible to "dissolve" a sub-assembly within an assembly

Hi!

I have a sub-assembly inside an assembly, and I created an explodeview and want to put balloons to all parts of the sub-assembly. Butit allowed only put one and the same number to every part withinthis sub-assembly.

So, is there any way to "dissolve" this sub-assembly to haveseparate parts, that I will be able to assign balloons to each one?

Thank you in advance,
Mark
