Mantaflow particle and mesh groups

Possibility to generate / separate particles and meshes to own groups and make possible to generate multiple liquids with own meshes and particles with different parameters (like viscosity and meshing resolution) in same liquid domain.

Those meshes (separated mesh groups or vertex gorups (vertex groups when same mesh should share multiple colors based on particles and mix them - like this: vimeo.com/130118827 - so in this one vertex group should be possible to link in shader nodes

While mesh groups would be handy for liquids which dosen't blend/mix to each other) and meshes should be able to have different sahders.

Or/And maybe it would make more sense to have viscosity, density (like oil and water - oil will be lighter and it will flow over water) and other parameters in emitters/inflow object - or - liquid domain could have group for emitters (to control viscosity by particles group/emitter).

What i would like to see - is possibility to create liquid domain with multiple different liquids which could interact each other (others interacting and mixing / blending vimeo.com/130118827 while other - mesh group should be just separated liquids that would only interact by physics but colors would not mix - own shaders and own data but some kind of particle data transfer would be handy for more complex liquid settings) - with different shaders, different viscosity, different mesh parameters etc.

Also particle based colors and UV Advection would go in this same group i guess: vimeo.com/178384597

Also smokes would need this or granulars (if those will be in mantaflow - at least there was this: twitter.com/sebbas/status/1321371647014805506 so also this kind of granular simulations should have possibility to separate particles / meshes and have uv advection and possibility to mix particles color data)

And now... Good night <3
