Able to ,manually change prices in the backend...

I would like to be able to change the price of a registered person without having to log in to my database to make changes.

For example, I may give someone a deal on registration and they register without a discount code, I can manually make the change to the amount it is suppose to be without changing it in my database.

I support this request.
Sometimes people forget to register with coupon code and ask for correction via email.
Since we handle those cases very customer friendly this feature would help a lot.

An email update sent to the registrant afterwards would be great.
