When you create the zone through the event, pretend like you've created a giant zonebrick that is centered around the brick you activated the event on, and can be changed through that brick. From here you can use it like any regular zone brick. You can make the zone have properties like water and movement resistance through the self>setzoneproperties or whatever event. You can also do your usual onPlayerEnterZone and such from the brick you created the zone with.
