Separate or space facing pages

[Alex32252670s8p0]

Hi everyone... here I am with another strange request.

When I work on a project with a few pages, I create it with single pages and then I place them side by side leaving 1 cm of space between them, so I can see the result at a glance.
But if I have a complex project with many pages, I create it using the side by side pages option. But there is a problem, when I export for printing, the page elements on the edges overlap and create problems.

My question is this: can a document with side by side pages be dismantled and the pages separated, but leaving them on the same plane? The separation must only move the right and left pages away from each other along the horizontal axis.
I leave an example image.

I tried some scripts but they don't work
