Grouping pages in WordPress

I have a WordPress site with English and French pages. I would like to group the French pages separately from the English pages and to have the French pages appear after all the English pages have been displayed. My first idea was to create a parent template FR and set up each French page under that parent template. This works but the issue is that the pages set up under FR are now in the middle of the list of pages as I have page titles that begin with letters before F and after F.

For instance, I have pages A, B, X and Z so the listing looks like
A
B
FR
–A
–B
–X
–Z
X
Z
I cannot set up the page using something like zFR so that the grouping is at the end of the list of pages because the zFR becomes a part of the URL and I need the URL to read simply “www.domain.com/FR/page_name”.

Is what I am looking to do possible?

Thanks.
