Sub emitter of particle system doesn't inherit mesh

I use sub emitter to stop particles from moving and rotating when hitting floor. Like replacing dynamic ones with static. So I use several meshes in the main particle system. When sub emitter emits particles they being picked randomly between those meshes. Is there a way to make sub emitter inherit mesh from main particle system? If not how can I stop existing particles from moving and rotating when they hit the floor? They are even if start speed is 0.

2019.1 exposes meshIndex as a property of each particle. Maybe you could use that somehow… but there is no simple built in way to do what you are hoping for.
