Question PEX Permissions - Update Permissions every hour?

Hi there,

I'm currently using PEX permissions to give my users on my servers permissions. I run a bungee-cord network and have all my pex files synced across the server using the same mySQL database. I'm having a hard time figuring out or understand if PEX allows you to auto-update permissions after "X" amount of time, for example an hour.

I say this because I don't want to constantly switch between servers and have to update the permissions for each individual server, I'd rather be able to go onto one server and add a permission and have it automatically synced across all servers, or have it updated every "x" amount of time. If PEX cannot do this, is there a permissions plugin that can? When I had my servers synced to the same mySQL database with PEX and removed a permission in-game it did not seem to take effect for the other servers. That's why I want to know what I can do to fix this.

Thank you for your time,
