No, I don't think so. When you start a hub, it is computer-generated thing depending on your topic that pinpointed automatically, the category open to Political and Social views.
However, you can choose the category by:
1. Click the Browse button
2. If you made an error, click the very light blue phrase "Start Over" and it opens up the "Choose Category"
3. Then, it is up to you to click OPTIONAL if you want more sub-category to truly define your topic. Otherwise, just proceed to LAY-OUT.
Hope this helps and if not, I suggest you call this out to the HubPages staff by emailing them. From my limited experience, they were very helpful.
Oh! I also want to add that most seniors I encountered here in HubPages write so beautifully about arts & crafts and travels; that means their hubs fall into that category and I enjoyed reading their hubs and learning from it.
