This would be very helpful, especially for two people working on a task together.
Commenting here for a customer - I believe this will help to streamline task completion processes alot especially when it is a team effort to complete certain tasks 
This is definitely a required option, since not all tasks are handled by a single person
Just chiming back in - still need this - even if it could be assigned to one “team” vs. multiple people - begging for something to have more than 1 person able to be auto-assigned a task without a clunky work around…
