SAB border margins or padding

I’m trying to allow for more text out to the edges of a border for an Arabic Script and have not been able to find a Styles adjustment to change this. Has anyone else been able to adjust this so there is not as much white space on the page and the text more closely approaches the border.

Thanks in advance for any pointers.

Something’s not quite right… Here is a screen shot from my app:

You can see that the text is a lot closer to the borders, almost touching it at the bottom. Maybe try a different border as a test? Maybe your border has some regions that are not quite white in the background, and SAB thinks it’s part of the border? Try cutting out the interior region with an image editor, maybe even making it transparent.
