The official 100-110 profiles have this feature built in without the need of a plugin.

Yea, that's it. But it won't work on a GB2 profile, you will need to convert the profile to a questing profile.
You can do this with using the InteractWith quest behavior, and having it in a <While Condition="true"> loop.
