I would like there to be a slider or some other input to adjust the vertical offset of a render.

I wanted to export renders of mob heads such as creeper, skeleton, etc scaled up to around the same size as a full block, but currently when scaling mob heads they are positioned really low and will be cut off on the bottom in the render (Set the scale to around 190 to see the issue).

Allowing the Y offset to be adjusted would allow me to raise up the render to fit into frame.
