Sorry, but I don't think this is possible...at least, not with the type 
of blob POV uses(are there other kinds that would make this possible?).
A blob object is just an isosurface, all points where the sum of the 
field of all of the components is equal to a certain threshold value. I 
don't think it is possible to exclude components based on the "branch" 
they are in.
