How can I set chunk transform in a destructible mesh?

I’m going to realize a feature of time reverse, where broken objects can go back to its original state. So I need to set the position and rotation of chunks in a destructible mesh, which are sockets and bones. So how can I do it?

I searched and got suggestions like this,

You could try moving the DM sockets/bone in script, or import the DM into a modeling program, export each piece, and replace the components with the matching single piece when interacted with.

But how can I do this?

Thanks.

I do t know. i think i saw someone export things as they occur in PIE by using Simulate and hitting Shift-F1 and pausing and selecting the mesh pieces or something.
