New UX: Edit/Change pre-existing Notification Action

[shreyak.garg]

With the introduction of the Notification action in the New UX, it would be great to have the ability to edit these actions once created. 

At the moment, once the notification worksheet action has been created there is no ability to tweak it further - you have to redo the whole thing again.

Hopefully this is very much v1 and all of this will be coming along in very short order.
