How to constrain ragdoll water buoyancy? (force)

I have this SkeletalMeshActor with water buoyancy (which represents a corpse you need to interact to solve a puzzle in my game). It has a Physics Asset on which I already applied constraints to try and constrain the ragdoll effect (you know how easy it can get out of hand… or arm… or leg… you get the point)

This works well enough for it to float nicely in water, but when I go and push it (or drag it, so basically when I apply some force) it easily loose controls as you can see in the picture. Is there a way to reduce the effect of forces on it? Damping maybe a solution?
