Add a To-do connector(Planner) in a channel with a default plan(A)
Create another plan(B) in planner
Change To-do list to the other plan(B)
Remove to-do connector
Add a To-do connector(Planner) in a channel and set the plan to an existing one(A)-> The issue at this point it's not possible to choose the existing plan, only to create a new plan
Notes: It's somehow possible to use an existing plan(A) in a new channel.
