We are running into nearly the exact same problem as the fellow in this post:
Description of the problem:
We are trying to add instances of the same Particle System using Skel Mesh Vert Location to multiple Skeletal Mesh Components within one Actor through blueprints and it will only appear on one of the components.
I noticed this post in that particular question and I was wondering if any progress had been made on this front:

We plan to change the module so that
you can specify any actor with it.
Also, we may add an interface for
specifying the component directly to
handle cases in blueprint where you
may have a multiple skeletal mesh
components and wish to specify a
particular component to use for
Any help would be much appreciated.
