Text Messages - delete multiple messages at once?

[LuvrGirl]

Is there any hack/tweak/program to delete multiple text messages at once by having some kind of little check box appear on a menu command to delete multiple message, kinda like this:

· Jerry
Hey, be there at 12pm
· David
See you later tonight
· Mom
Dinner at 5pm

(The bullet points would appear as little boxes we can check off)

This way the check boxes would only appear once you select the menu command to delete multiple messages and it would allow you to put a check mark in each message you want deleted.

Anybody have something like this??

Thanks!
