A way to "correctly" print double-page spreads?

[instinctive.de]

Hello!

I'm planning to do a very "spontaneous" christmas present, and in hopes that I won't get the "General error in the PDF filter" on export, I plan to do it in Xtreme

My question: I want to print a small A5 brochure (portrait), on A4 paper (landscape), with double page spreads. Is there any way to get "correct" page ordering from Xtreme, so that it outputs:

Page 8 | Page 1 (on a single landscape A4 page)
Page 6 | Page 3 (on a single landscape A4 page)
Page 4 | Page 5 (on a single landscape A4 page)
Page 2 | Page 7 (on a single landscape A4 page)




Probably I'm missing something obvious, but I can't find the option...
