problem with rigged assets

[karlisss]

hallo.
to fasten my workflow and rigging time i decided to split characters into building blocks.
Torso
Head
Hand

each building block is rigged with actions and smartbone to switch layers etc. Head have 10 different drawings to get rotation, same goes with hand.
so each BLOCK contains
1. Bone layer with smartbone
2. and switching layer folder
NOW
when i want to put together a character things get messy...
i only managed to make it in this order:
1. import all blocks to scene
2. create MASTERBONE layer
3. drag all bone layers under Masterbone
4. group each bone layer in seperate GROUP layer (because i cant bind to bones a bone layer)
5. then bind grouped layers to each bone of masterlayer

problem is:
my smartbones for each bone layer (for each building block layer) are awailable only when i am IN particular layer

question IS:
how to make smartbone from each grouped layer in MASTERBONE layer ?

i hope you can understand what i mean.

Smart bones in the master layer can control smart bones in child layers.
