Include macro and content archiving

I’m coming across this problem:

We have a page, which includes a couple of other pages via the include macro. At a certain time, we want to have a snapshot of this page and copy this snapshot to an archive space.
The problem we encounter is that when one of the included pages changes, also the parent page changes (this is by design of the include macro).
Is there a way to “render” the include macro as static?
We have tried a workaround of exporting the page as Word, and importing again. This basically renders the include macro content statically into the page. However upon importing the formatting changes.

Any hint on how to approach this?
