I'd love a preset for co-op bundles that splits the developer cut distribution according to the retail value of their games in the bundle. 

For example, if I have a bundle with 3 games from different developers with retail values $5, $5, and $10 respectively, the preset would set the cut at 25%, 25%, and 50% for the respective developers.

Obviously the above math is super easy, but it gets complicated when you have more products at different price points.
