Make promo codes able to copy from one event to another; Make a limit of number of tickets per person promo code applies to

We offer certain families a promo code that will get them 4 free tickets to any or all of our shows. As Ticket Pro works now, I cannot copy that code to a new event, which means I have to recreate it a LOT! It would be great to be able to copy (even within an event, a similar code could just be edited). Also, it would be great to limit number of tickets a code applies to, not just a minimum required tickets or a maximum use.
