Here is a manual hack, save the prop to a library of choice, but also save the geometry in a runtime folder of your choice.

You can cut and paste this text, just change the "your folder name:your obj" to the correct info (be sure to get the brackets!):

{
    storageOffset 0 0.3487 0
    objFileGeom 0 0 :Runtime:Geometries:your folder name:your objfile.obj
    }

I hope this helps.

Cheers,

Davo
