Move tasks to backlog from a project

[#1]

Description - We would like to have functionality to move tasks to the backlog from the project level while in the project schedule. 

Why is this feature important to you - We work in agile mostly and many tasks have to be removed from iteration back to the backlog.  

How would you like the feature to work - Select the tasks, click on three dots, select move to from drop-down and have backlog as an option of where we are moving the tasks to.

Current Behaviour - No option to move tasks a backlog from a project.
