I cannot seem to find a style drawer front that suits what I generally produce for my bookcases. I need a flat panel drawer that is very similar to the slab drawers that I have applied to this bookcase, but I need it mitered with 1.5" style and rail.
Is it possible for me to edit these slab drawers into what I am looking for?
Sounds like you are going a bit overboard for your renderings. It also sounds like you are looking to have a wide edging for these panels and not rails and styles. If I were doing it I would just created 1 1/2" thick banding material and then apply that to the slab drawer fronts. It won't give you miters, but it should be close enough for the look.
Go to settings/prefrences>define stock materials>banding stock, and create your banding stock here.then when in the door/drawer editor under door selection set it as your default banding stock
