I've now wrote 3 Hubs based on the 4 new Apple Product's (iPhone 6s, Apple Watch, Apple Pencil, iPad Pro) I still need to write to review on the Apple Watch. But is there a way the add groups. Please let me know. If not that's fine!
Sure. There is a tab called Groups where you would be able to create a Group called Review. Once the group is created, once in edit mode on a Hub, on the right hand side, there is a section called "Display Options" which allows you to add your hub to any of the groups you created.
Topics (at the top of the page) are different as they are maintained by HP and you can not add Topics. You can assign a hub to any existing Topics.
You can help the HubPages community highlight top quality content by ranking this answer up or down.
