Yea I would like the same. At the moment I use a status column with names for this reason… and I read here others use the drop down column, but you need to create those and modify them everytime you want to remove/add a member. The people column is much better suited to select names, that is IF you could turn off the assignments/notifications…
This also would be very handy with my feature proposal. Maybe you can drop a vote if you like the idea: Automation: Assign whoever is in this column to that column - Feature requests - monday Community Forum
