Duplicating Existing Twinmotion & Revit files under a new direct link. (Keeping all assets!)

All of the landscaping was done with TM assets, only the house itself was completed in Revit. So, I’ve tried duplicating the Revit files for 3 different design options that I may need to come back to, however the exporting or linking to existing duplicate TM files with the landscaping already completed is where I struggle.

I think as soon as I duplicate the Revit file all of the assigned TM assets are reset immediately, and thus exporting datasmith would have me repeat all the landscaping again, so not sure how to get around that.

It’s not a big deal for this project but for future projects that require multiple design options in TM renderings I’m wondering the bet way to go about it now.
