Checklists V5.0 - P65 Ctrl-drag

Hi all, I’m trying to Ctrl-Drag from the Add button to the Checklist View Controller but I’m not getting the option to pick addItem from the popup (under Sent Actions). Instead I’m getting a pop up with fewer choices. screen shot below.
Can someone clear up what I may be doing wrong with this as it seems straightforward but still no go on this end. Thanks in advance.

Issue Resolved! Turns out the class needed to be added first before Ctrl-Drag.
