The last update limits what equipment is added as an alternate or substituted. In order to add an alternate or substitute an item the category and subcategory must match. This is an odd limitation. For an example we use subcategories to separate Da-Lite screens. Category is "Projection Screens" and our subcategories are the different screen types like "DescenderPro" "Advantage Electrol" etc. We want to present an alternate screen without having to make all of the screens the same generic category and sub category. At first I thought it was cool that the list of options was limited, but then I realized there was no way to search and get the the entire library of items. Not cool!
