Brochure or pamphlet printing

I'm trying to create a document as a 4 page A5 pamphlet or brochure to be printed on a single piece of A4 paper in landscape orientation. Front side of sheet should contain page 1 on right and page 4 on left. Rear side of sheet to contain page 2 on left and page 3 on right. Then when I fold the paper I can read it like a book. Easy enough in page layout - just create the four text boxes. But here is the problem: I want the text to flow from page 1 to 2 to 3 to 4. Pages lets me link text boxes 1 to 2 to 3 OK. But when I link in page 4 Pages insists in reordering the pages as 1 on left and 2 on right of front side. Is there any way of telling Pages I know what I'm doing when I link the text boxes together! Reordering the text boxes doesn't help - it does not seem to allow 1 & 4 on the same side. I can achieve the effect I want in OpenOffice - edit the document as if it were four continuous A4 portrait pages, then tick option Brochure in Printer settings -> Options. The printout is scaled down and printed exactly as I want, 4+1 then 2+3. However Pages does not seem to have that feature. None of the layout directions available with pages per sheet 2 gives me 4+1 then 2+3. I don't mind which technique is needed to achieve the effect I want as long as I can do it somehow. There was an old version of Pages which did allow text boxes to be linked in the way I have described.
