I would like to create this in a people process flow, whereby person enters the lift at Level 1 and exits at Level 3. However,
1. the lift should be unoccupied until it reaches the original level. (Level 1)
2. lift should pick up another person from the Level 3 and return to Level 1.
3. lift should pick up another person from Level 3 and another person at Level 2 and return to Level 1.
How do I do so?
