Un-Grouped Topics

One of my favorite features in the Glow Community is the groups. I love being able to see just the types of posts I want to see, and avoid the ones I don't. 
I've noticed that it is possible to create a post without adding it to a particular group. That post shows up on everyone's "top" and "new" sections, which are the sections I check the most frequently. I find this to be a bit of an annoyance, as they are usually posts I don't care to see, and wouldn't show up in the groups I am in. 
I would love to have the possibility to block "un-grouped" posts from showing up in my "new" and "top" sections. If anything like that would be possible, I think that would be great! :)
