I was able to figure out how to setup puias Unsupported repo which is maintained separate from their OS build. Here's my puias.repo file.
name=PUIAS Unsupported $releasever
Please note: I use yum-priorities to keep my repos tidy and I recommend others do the same. When I installed a rpm (e.g. qrencode) from this repo it complained about not having the GPG signing key so I had to use the --nogpgcheck option with yum. If someone can find their GPG key, please let me know.
