Hi

For this you need to create different phases where different groups can be assigned.

Phase 1 Group 1  act, when done, the Automation can move the card to Phase 2 (other automation to clean up the Assigned people and assignee new ones) where Group 2 can be Group 1 assigned is cleared and Group 2 must be assigned and this going on until finish all phases.

Good luck

Hi!

Another option for this case is to use a child pipe (pipe 2)

When the card is created/moved on pipe 1, creates child cards for each responsable on pipe 2 and when all of them are finished moves the parent card on pipe 1.

I hope it helped.
