Model Rotation Reset

[unclechunk]

Is there a way to reset the model position to the position it started when uploaded?
I know we can set the rotation but that's based on its current position, so if it's been moved via the mouse or similar then it's not rotating from a default point. Ideally, the rotation would be from the loaded-in position.
A set_position_default would be great, if there any way of doing this?
Is there any position information saved when the model is loaded, so we can return to that position?
