Customising pdf export

Hello

I am trying to export a pdf with larger frames (over half the width of an A4 with 4 frames set in a vertical column). I’d also like to thicken the frame line and move the notes to the right so that the frames are the only element on the left of the page. This is to create a standard display sheet for live action film storyboarding.
I am currently amending the Japanese Format template but struggling to do make the changes I need.

Any help would be much appreciated.
Many thanks.

Jake

I’d love to change the column width for just one column (the art panel) as well! Any solutions yet?
