Pandora mobile: add "move to" and "shelve" for a month"

i love Pandora on my Blackberry however the lack af ability to "shelve" a song that i don't want to hear forces me to eat up my "fast forwards" and kills the experience as it means the same song keeps coming up.

In addition, i have discovered a lot of really cool new music that i really like but don't necessarily want in the playlist I’m currently on. i would love to "move to" another play list. without it I’m forced to simply "thumbs down" the some and forget about it =(

Long story short, I'm just looking to have the basic web interface capacities extended to the mobile application.
