Recursive RBD fracture with RBD Material Fracture and RBD Bullet solver SOP

[NoaX]

Hello, 

I  need a way to fracture GEO recursively/dynamically using the RBD material facture (No clipping, or cut); (I have built and seen methods for splitting boxes using a loop inside an SOP solver inside a DOP, but have not seen a version using RBD material fracture or the new RBD bullet solver sop) 
 

Here I have a basic setup with gravity and rocks crumbling, I've added an attribute transfer to visualize a green zone in the middle. The goal is to say, at frame 120 (Or any random frames) for anything that's green or inside a threshold to split into new parts dynamically while retaining the settings of rbd material fracture if possible. 

 

Rocks in green 'split into new rbd material fractures,' rocks without color remain RBD but do not split.

Ideally with the RBD bullet sop solver, no DOP network approach.
