Ability to disable job role assignments when unassigning user

[#1]

Currently when you unassign a user from a task/issue, it automatically fills in the assignee with that user's job role. My company has never used this feature and it just creates extra work and confusion to either remove that job role or to see it in the assignments. It would be great if this is something we could disable in the setup area.

I agree that this may be "logical" functionality in some cases, but it also proves to cause confusion when the task/issue is being assigned to another role.   In our case, our teams Scrum.  They unassign the user from the Scrum board but the role remains as the primary assignment.  When they try to assign it to someone in another role, they get an error that the task cannot assigned because they do not have the role.  The only way around it is to go into the task itself and then adjust assignments from there.

I think this feature can be helpful, but maybe this can be controlled through a group or project setting.
