Import Export of Scanned mesh in Quest 3

Hello ! We have seen the scanning of indoor spaces and adding 3D boxes in the mesh Using Meta quest 3. I was wondering

> is it possible to upload a pre scanned room into the Device?

The scan can be taken from the Meta Quest 3 or Some other tools that generates similar objects. In other Mixed Reality Device (mainly Hololens 2) we could export the scanned mesh as a 3D object. Unsure about the uploading though.

> Is there any information regarding exporting and importing ? Is it possible in Meta Quest 3?

purpose of this query is that I dont want to have one gigantic mesh for all rooms. Also for demonstration purpose scanning and making the mesh on the spot may take more time than pre populating the hardware with data. [Unsure whether this idea defeats the purpose of the current scanning feature of Meta Quest 3]

Any suggestion or information is higly appreciated.
Thank you!
