How to create a poudriere jail for a specific git hash of 15.0-CURRENT?

I just updated my pfsense box to 24.03_1 and according to this page:

     https://docs.netgate.com/pfsense/en/latest/releases/versions.html

23.04 is built from 15.0-CURRENT@a5a965d75934. How do I create a 
poudriere jail for this specific hash?

I see how to create a *newer* version:

     poudriere jail -x -c -j pfsense2403 -a arm64.aarch64 -m git+https \
         -U https://git.freebsd.org/src.git -b releng/15.0 -v main

which I assume uses the most current hash.

Looking at the -m flag I suppose I could clone 15-CURRENT, "git checkout 
a5a965d75934", and then use -b -m src=path? Is that my best option?
