If you already have the edge styles created, then when you go to the worksheet you will be able to click on the menu on any one edge. That edge will become highlighted in the preview. You can then click on the "Edge Style" currently listed (it will be *NONE* if you haven't assigned any yet) and a dropdown menu of all of the edge styles in defined in the drawing will appear. Pick the one you want for that edge. You can do the same to the "Edge Cut", "Overhang" and "Angle".
