We have the same concessions applicable to all membership levels. Creating and applying each concession to each membership level is time consuming, especially when having to enter a different price for each. Having a % discount option would be much easier as it would then calculate the price for me. If coupled with the ability to select which products/membership levels it applies to it would save a lot of time (i.e. a multiple choice list similar to the Club Structure list where all teams can be selected that the discount or concession needs to be applied to).
