Looks like I figured it out. Cloning the default event wasn't the way to go. Creating a new Rule starting with User Disable allowed me to add groups to define it down to the info I wanted.
My Rule is as follows:
UserDisable
Group: UserDisable.EventInfo = *Account Lock*
Group: UserDisable.DestinationMachine = the DC I wanted the info from.
If anything hopefully this helps someone else out.
