What Linda has mentioned will not work for your PROFILE, but it will work for a grouping link at the bottom of your respective hubs.
The hubs that show at the bottom of your profile are generated by the topics you write under. As you publish more hubs this section will expand. You can however create links to the hubs you want to feature. You would need to create a custom link for this. If you are interested in doing this you can take a look at my profile to see how I did it and where I have a link to a tutorial. I wouldn't want to list a link here :)
I hope you figure out what you are wanting to do :)
