Changing realm defaults


I wanted to know if there is a way to change the realm defaults. I want to add the event listener provider to listen to login and admin events by default to all realms created like jboss-logging is. Right now, I have to go and enable the provider manually, but I would like it to be added by default to all my realms.

I know the defaults are set in RealmManager but I cannot change that file. Is there any other way of doing this?
