Can one create categories of categories in capella? This would be a way to create and logically group subsets of categories together. It would also reduce further clutter on diagrams by simplifying them on a higher level.
E.g. I created two seperate categories, each containing 2x functional exchanges. I now want to create a new category that contains these two as subsets.
Possible? If not, how would I go about creating such logical subsets?
