Drag between taskbar rows

I can only fit 19 apps in each taskbar row.  After that Windows adds another row and has up/down arrows on the right side I can use to scroll between rows.  Dragging apps around inside a row works great, but I can't figure out how to drag them between rows.  It would be nice if I could drag them to the up or down arrow, hover there while it goes up/down through the rows (either variable speed or maybe 2 per second), then drag & drop it where I want inside the row.  Thank you.
