Deleting Messages

Has anybody else ever wanted to delete an entire conversation for one reason or another (whether you don't like the clutter of all of those messages in your messages or you had a falling out with someone and you don't want their messages lingering around) Currently you have to delete each message manually (as far as I know) and cannot simply delete an entire conversation (if there is a way to do this please by all means let me know) So if there is not a way to simply delete an entire conversation I would suggest adding a way to do that.
