My Carrier Item gets stuck doing a round of pickups

From Planimate Knowledge Base

Q:   I want my Carrier Item to do a regular "round" to do pickups, but it gets stuck at the first empty PickUp Object.

A:   Ahead of each PickUp Object, place a Switch that 'prefers' to go to the PickUp, but which can move on to the next PickUp if the first is empty.
