I really like Sushiboat's suggestion!!! (I'd like to see movement queues in general!)
However, having "0.5 level"-sites would be nice too:
- level 0 - found automatically
- level 0.5 - found automatically if a mage with the proper path is present
- level 1-4 - need to be searched by a mage of proper path requirements (as it is right now)
