Hello D. Nagy

You can right-click on a part or component in the Structure Tree and choose Source and then Update Source from CAD.
 

When starting with a native CAD file, you can replace with a new version of the same CAD file in your simulations.

But even this feature does not synchronise with an active session but only opens a saved file.

I hope this helps.
