Currently when you drag and hover over an application dock item and wait 1,5 seconds (thumb suck delay) with the mouse down, it will behave the same as a mouse scroll on the dock item.
After getting feedback from developers, I will attempt to have the "drag event" open up other instances if the dock item has more than one instance of the application open. (i.e: as if the user did consecutive mouse scrolls 1.5 seconds apart.)
