Is there a way for the auto balloon function to target only sub assemblies?

I have a large assembly that is composed from quite a few subassemblies. When i try to use the auto balloon function, it targets all the parts in the main assembly, which means there are 400+ balloons on the drawing. So, is there any way for the auto balloon function to target only the sub assemblies, beside opening every assembly and changing the child component display in Configuration settings.
