my goal is to restructure the dimension "site section" in Adobe Analytics. At the moment, there is mess of many irrelevant site sections and I would like to boil them down to maybe ten main site sections and some sub site sections.

The classifications can be set up as per your needs and fantasy 🙂 Here are a few examples:
