Absolutely! It's called PhotoAlbums+ for iPhone/iPad. Just search in Cydia for PhotoAlbums+.
It's a paid tweak, but it's worth every penny to eliminate the asinine way Apple deals with photos on the iPhone.
With the tweak you have options. You can keep the same method, or you can move photos (which is what you and I both want to do). Additionally, PhotoAlbums+ will also allow you to prevent automatic uploads of screenshots or pictures you take with the camera to your Photostream. This feature allowed me to enable Photostream again as I had it off because I didn't want this happening.
The tweak is iOS6 compatible. Hope that helps!
