That's great!

Have you tried poking Thunar's developers into merging such a
feature?
This is where the developers would like such things:
https://docs.xfce.org/xfce/thunar/bugs

It'd really be the best place for a setting like this to land and
benefit all Thunar users out there (which are not limited to
Debian-like or even Linux, but also include the BSDs).

Cheers!
