Changing position of full screen

I’m just starting to use Scrivener, and I was wondering if it is possible to get some more fine-grained control over the position of the full screen? I can see that there is a menu at the bottom where you can set the position to left, centre or right, but is there another control somewhere that give you more positional options? I’d really like it set in-between left and centre.

No, as far as I’m aware, that’s it. But you can change the width of the paper which might allow you more fine-grained control.

Yes, I know you can change the width of the paper, that helps a bit (that’s a nice function), but it doesn’t get the screen into the vertical position I want.
