Unable to associate action with window

Service Desk 7.8, Incident module

We have an action, Ready for Pickup, that I want to associate with the Resolution window so that a Resolution is created for the incident.  When I go to Incident Management\Incident, right-click on Resolutions, Manage Actions, the option to Add an action is greyed out.

I had found this article on the subject that got me as far as above:

Step by Step example - How to create a new action so you can "Add Task Attachment" when in a task

Any help would be appreciated.  Thank you!
