You click a brick name out of a list of bricks, and click set as portal. Then you select from list when you touch a brick. Not that hard.
Sounds exactly like events.
If Trader were to release these as they were in v8, I'd be disapointed, maybe if he added some cool feature to it, then it would be a good add on. but it really isn't useful, stop trying to make a point, Azimuth, nobody thinks it's of any use when you have events.
