You mean other than using the drag-and-drop behaviour?
You'd have to manually create the behaviour then, but instead of updating the object's position to mouse.x,mouse.y every tick (or as the mouse button is held down, specifically), use lerp to get a smooth movement: lerp(self.x,mouse.x,0.5);lerp(self.y,mouse.y,0.5).
The object will appear to lag behind the mouse, but adjusting the lerp interpolation to whatever is suitable will help minimise that while still smoothing out the movement.
Example capx.
