How to pose a ragdoll rig?

I’ve set up a ragdoll rig, using some of the tutorials found on this forum and so far so good, all works as expected. However, I want to be able to pose the ragdoll prior to the simulation running and keep having issues.

Firstly, I thought I could use a child-of constraint to make the hit boxes follow an armature, but this creates an odd jumping issue when the simulation takes over.

I’ve also tried creating an armature and vertex groups for the ragdoll’s hitboxes, but the armature continues to influence them, even when the simulation takes over, which leads to undesirable motion!

Are there any other options?
