Ability to receive options set event

I'd like the ability to add a listener to the ConfigListener that receives an event when all options have been set (localToApplication).

The problem is I have several config options and if any one of them changes, I need to reload sections of my application. I don't want to reload if any one option is set, but the ability to mark a dirty flag if any change, then receive this new options set event to determine if I should reload.

If there is another way to do this, I'm open.
