Sort Bullet/Numbered List

I have come across this a couple of times where I will create a list of items and will add or remove items from that list as and when necessary. However it would be easier if the list could be sorted a click of the button. I know a easy solution is to always keep the list sorted by adding the item in the correct place, but there are times when I'm in a hurry and to put it bluntly can't be bothered to work out where an entry should fit.

It's just a thought!
