I am working on a kitchen with stacked upper cabinets, which will be built custom as one unit. Is there a way using one upper cabinet to only change the "upper" doors to glass. I am working in X17 and have created the stacked door look with one cabient, but cannot get just the upper doors to change to glass. I have searched past topics. Will I have to build out as two seperate cabinets to accomplish this? Thanks!
