I like putting most of my stuff on sale at the same time, but I don't necessarily want the same discount applied to all of it.

Right now I have a 75% off sale for my older projects, and a 35% off sale for my newer projects.

It's a little awkward and obviously all the games can't be bought togetherat once this way. Being able to set different rates for projects in a sale would mean I could include everything in a single bundle without worrying about devaluing my more recently released work.
