Fusion does not currently support this capability. However, Fusion does support the ability to query the model through the API so technically it should be possible for someone to write a script that would query the model and then create a script that would re-create the model. It wouldn't be trivial to write and there would be a few fringe cases where you can't get everything you need through the API but I think it should be possible for most models.
