Item Accessory Cut sheets in Submittals

There doesn't appear to be a way to have item accessories show up in a submittal with their parent items. Instead, they show up alphabetically in the overall list, as if they are actually separate items. (Unless i'm not seeing that feature). It's causing confusion when engineers review our product submittals, because it is not readily apparent that the accessory comes with the parent item. Is there a way to have all the cut sheets for kits show up together?
