Is your feature request related to a problem? Please describe.
Theres no easy way to quickly edit the bungee messages.properties file and reload it without rebooting the bungee server while everything is running, specifically when the server fills up I wish to be able to change the server full message.
Would be nice to also change the restating message live too depending on changes/maintenence periods.
Same for the server_went_down.

It would just be nice to be able to reload this file live.

Describe the solution you'd like
A file in the same formats you use to easily use color/gradients and to reload these messages live without rebootin the server.

Describe alternatives you've considered
Restarting the bungee every time.

I don't think I fully understand what you're asking for, but from what I do understand it seems completely out of scope for MiniMOTD

closing due to lack of response

Live reloading of bungee messages.
