Coupling Rocky is pretty easy and is controlled from the Rocky side. It'll see capability upgrades etc over the coming versions, we can do a lot more using user coding. I'm one of the European Rocky specialists as part of my more general remit to cover the weird stuff (just don't ask me about modelling cars & aeroplanes). 

There's a volume injection in 2022 for DPM, use that, but remember to keep volume fraction low to avoid packing issues. With Eulerian (not DDPM) just patch in the solids at a bit less than the packing limit.
