Greetings,
I'm working on a simulation, kinda a classic one, with Viscous Chocolate been poured on Yogurt. Basically a Viscous Liquid Collides with a more Viscous Liquid and they BOTH get deformed in some way the Chocolate more, the Yogurt less.

I did the Chocolate pouring and it looks really nice at first, now I need to replace the Ground plane with the Viscous Yogurt.
I had the idea of using Narrow Band for the Yogurt surface and using double viscosity than the chocolate.

But in my bad luck you can't Merge 2 Flip Solvers.

I've read that you can use 2 Flip Objects though, but how do I import the Narrow Band in one Flip object and the other Flip Object points at the Emitter from Volume Source ?

Basically, how do you have 2 different Fluids(with different attributes), one imported as Volume Source and the other as Narrow Band?

Thanks in Regards

To help a bit, I want to achieve something like this:

Is it possible to make it with yogurt as Fluid, or should I make it as soft body ?
