1. After marking a transition as common, how can I use that transition in another place? In this example here I want to go from "Traitement" to "Closed" using the transition "Resolved" - which is a common transition. How can I go from "In Progress" to "Closed" using the same transition? 

2. Can I add 2 different transition to 2 same stages? EX: I want to go from "Open" to "In Progress" with 2 different transitions "Non-critical" and "Critical - non general"

Thank you for advising!
