I'm not sure if this is a feature or not but for all of those who own Digital Cable or have Satelite, or are just familiar with any built in program guide that you use to see whats on tv.

Yes, picture in guide was a nifty addition. But I, like a lot of people flip through the 500channel guide finding like maybe 4 or 5 programs that i'd like to watch that are on. Is there someway to flag those channels as i'm scrolling through the guide, so when i'm done looking i can just quickly view those channels when flipping back and fourth, like a filtered guide for your fav channels that are currently on, and is easily reset-able.

I know you can customize your guide to display only the channels you want, but that takes time. An on-the-fly approach would be sweett!
