Fold pattern in Preps for Landscape booklet, stapled at the top

[redlik]

Hi,
I presume all the pros will know it straight away but I can't figure out how to create a fold patter to A4 landscape book but stapled on the long top edge, Something like wall calendars. I can rotate/flip the pages in the fold patter window but the spine is kept at the short, left edge no matter what I do.
I've tried with 16p, 8p, and even 4p sections but no luck
I'm attaching the screenshot - 2 pages on the left is was I'm getting so far, the desired layout is on the right

Any help appreciated
Ralph

Use a portrait imposition. Rotate the PDF pages in Acrobat or your workflow. Usually all 90 CCW except the back cover which would be 90 CW.
