Hi Rory,
You are quite right 
Although we can’t share any specific dates, we are working on this and as Sebi mentioned, there will be a more direct way to apply padding/margins to application pages soon.
Glad to hear you managed to get it to work with the vertical sections though!
As always, thank you for the feedback and please feel free to reach out again with any other questions/concerns.
Have a great day,
Anna
