Printing Page Spread Thumbnails

[deedub]

Is there a way to print thumbnails of page spreads, outlined, in pairs, so the spreads are each clearly defined? In the very old days, PageMaker did this very nicely. I can make a cheesy workaround for now, with outline rectangles at the extreme edges of the master pages, but when printed, all the spreads run together as an evenly-spaced array.

I see that I can adjust the V-gap, in the N-up setting, but this will separate each page, not the page pairs. Thanks for any ideas...
