Autorelease of task which was accepted

Hello team,

is there any best practice on how to auto-release a task which was accepted by somebody from a specific group after some time, lets say 1 hour. In my case i have a group called "Processors" which contains approx 50 users. When a task is assigned to this group the users accept a task a work on them. I want to ensure that when somebody from the group accept a task but not complete it in 1 hour it will be autoreleased and reassign back to the whole group so somebody else can take care of it.

Thanks
