PEX %<custom> API help

Hello.
I have a simple request for the people that know the pex api, I would like to know how to create my own custom prefix and adding it to permission groups, such as %prefix or %suffix, I would like a %<custom> with my own string I created. Here is an example of what I would want it:
(in permissions.yml in PEX)

Code:

message-format: &7%<custom>&8%prefix%player&2 >> &a %message

If anyone could provide help, it's always appreciated

 

thebmanswan541 I'm not too confident I know what exactly you want but from what I understand you could just use the String#replace() method to replace lets say "%playername" with player.getName();

 

Use this:

Code:java

getConfig().getString("message.format").replace("%prefix", prefix).replace("%player", playerVarible);
