Controlling IPFire mirror list server-list.db

Hello,
Seeing that I have an excellent download speed with European based mirrors, I am searching for a way to tell to pakfire to always use my server-list.db (I edited it).
For example, I want to avoid to start a download from far away servers like Australia one (.aarnet.edu.au) or Ecuador one (cedia.org.ec)…and other Asia based servers.

I already tested manually some of Europe based servers and I have a limited list of those that ensures me an excellent throughput.

I am interested in stopping server-list update.

For clarity - I know I can use /opt/pakfire/etc/pakfire.conf to use only one mirror, but I am interested in more than one, and I believe that is doable by using a custom server-list.db and stop pakfire to update this server-list.db file
