Summary: I would like there to be different size options in the duct routing preferences that allow you to select different sizes for the width and height of a duct (applies to rectangular and flat oval duct only)

Description: Currently, the routing preferences allows you to select which duct sizes to use for a particular duct type. This is great, in theory, and is fine for round ducts and pipes. The problem arises when we have rectangular ducts that have a different width and height. We use one duct type for rectangular ducts 12" wide and larger and one duct type for 10" wide and smaller. For the 12" wide and larger ducts, if you de-select the sizes 11" down to 3", it doesn't let you use those sizes for the height either. This is a problem because the routing preference doesn't depend on the height, only the width.

My wish would be that, for rectangular and flat oval ducts, there would be a separate duct size routing preference for the duct width and the duct height, not just "duct size".
