Are there variables (or placeholders) that can be used in the messages section of spigot.yml? Specifically, I'd like to change the unknown-command message. Currently it's: Unknown command. Type "/help" for help. And I'd like to change it to two lines with placeholders like this: Sorry %player_name%, but we do not understand: %command% Please type "/help" or visit our wiki for a list of commands. Is there a way to do this?
