Landscape Page Setup, iOS

I am using a new way of developing characters. It would be great if I could format a document (1 sheet character description) in landscape. Using the Legal setting, i could then have something resembling a wide spreadsheet, suitable in width for contrasting comments laid next to each other.

Is there a way to make a sheet wider in Scrivener, formatting it for landscape as I am working on the sheet?

Thanks!
