Sitemap in Omnigraffle won't move positions in auto layout mode

Hi Everyone,

I am having more trouble with sitemaps again.

If I use auto layout for my site map, the map will always be in the same position no matter where I drag it to. IT snaps back to its own preferred position. I get that and that’s cool BUT can I move it a little higher in the page?

Is there a way to at least give it padding or margin or something that will help me move it either centered on the canvas or away from the left hand edge more please?

Thank you.
