Update a board with a new group

I have a board with a list of 100 elements, each of which has an end date. From there I manage some automations: Board A
I have another Board, board B, with an “element group” used as a template. Whenever an element in board A is subject to a change, I would like it to move to board B and take all the elements of that model.
Monday’s automation allows you to move the item from A to B but it does move it to an already existing group without giving me the option to create a new one, as I would like to do.
How can I automate this?
