Scenario...
Once a motion is put on the floor and seconded, and we move into discussion - hands are raised (virtually, for time being) and a list/queue is established for order of discussion on the Motion. Then a Motion to Amend is put on the floor, seconded, and moved to discussion of the amendment.
So...
Does that start with an entirely new list/queue of people to speak on the Amendment??
And then, for the entire list/queue of the prior main Motion - is that list “frozen” and recorded in order in case the amendment fails, and we return to discussion on that main Motion?
