Add Agent Ransack Icon To Classic Start's Windows Explorer

I read in Classic Shell's FAQ that I can add a button for e.g. Agent Ransack to my Windows Explorer toolbar, to do searches. I know how to add that button so that it launches Agent Ransack, but I want Agent Ransack's search location to be the folder in which I clicked the button. I suspect that I need to edit the shortcut properties, but with what?

I can currently right-click any folder and select "Agent Ransack" and it will use that folder as the search location. But I want the ability to click a shortcut while a folder is already open (otherwise I have to go up to the parent folder, and then right-click the folder and select Agent Ransack, and then down into the folder to open it up again).
