Price groups for card sets

Let’s say you have a card set “for rent”. It will be nice to have an option to save and restore 2-3 groups of prices for the cards in the set so you can list them for rent fast.
After selecting the price group, let the user adjust the prices if required and give him the option to save the price group (create a new one or update the current price group).
For example I would like to have 3 groups of prices for the start of season, middle and end of the season.
Thanks and keep up the good work.
