Task based on AoR

Hi all,

If i assign a task based on AoR and it allocates on multiple users with the same AoR, when one of this users complete this task Is it possible to notify other users and track the name of who performed the task in the system?

Because at the moment when i do this, in the task list only appears the completion date but not the performer's name as it shown below

There is some way to show also the performer's name here?

Thank you
