How can I re-express a wrapping surface or contact geometries in a different frame?

Is there a way to re-express wrapping surfaces or contact geometries in a different frame after creation, similar to path points?

Wrap surfaces and contact geometries, themselves, don't have a transform, per-se: they just weld onto the frame it's attached to.

The easiest way to "re-express" them would be to:

• Add an offset frame to the frame they're currently attached to (e.g. via the right-click context menu)
• Attach your wrap object to that offset frame (for contact geometries: change the socket in-UI, for wrap surfaces, you'll need to manually move the wrap surface into the WrapObjectSet of the PhysicalOffsetFrame, because wrap surfaces are legacy and do not use sockets.
• After re-attaching, your (wrap/contact) geometry should be in the same location as originally (the offset frame hasn't been offset yet)
• Right-click the offset frame, Sockets > parent, change the parent to what you want to re-express it in, ensuring you tick the Re-express in new frame option
• The PhysicalOffsetFrame should then be attached to the new frame without jolting around
