The editor plugin is really good to add hotspot, but I don't think you can add directly the action.
What I usually do is to use the editor plugin to create the hotspoy, then go back to the xml editor (also in the editor plugin) then find out the hotspot I have created and copy / paste it in my XML source file. Finally on the "onClick" pattern, I manually add the action I want for that hotspot.
Hpoe this helps
