Duplicates of Draft Revisions

Hi

Thanks for an excellent plugin, that has made our workflow MUCH better.

I have duplicated some draft revisions, using Post Duplicator, in the process of using the new layout and design on that page, for multiple other pages and now encounter this problem;

When I publish the duplicated revision(s), it/they overwrites the original post, which is not the one that needs to be overwritten.

Once/If that initial revision is published, how do I publish the other duplicated draft revisions, all based upon the same original post/page, without losing the original post/page each time?

i.e.: Is there a way to prevent a specific revision from overwriting the page that it was based upon?

The page I need help with: [log in to see the link]
