Ach, ze French...:)

I see what it is you want.  It wouldn't be too hard to have a 'template
page' behind every page printed, but Dia has little idea of page numbers.
In fact the split into pages is more of a printing hack than something
closely tied to the diagram itself, and it'd require a fair amount of
hacking to get page numbers accessible.

You're saying you want some surrounding box-thing?  Can you point us to an
example of this?

At the moment, this is way beyond Dia.  With no page numbers available, and
no way to indicate them even if they were, we can't do this.  (La)TeX would
be able to do this easily, but it's a very different system.  I have hopes
of more interaction with (La)TeX, but in a different (pageless) way.

That kind of naming seems rather fragile, tool.  Doesn't that mean that if
an extra page is inserted, all references to the elements are wrong?  But
if that's what you're working with...
