An open plea to Solidworks

I have been looking at the upgrades for Solidworks 2017 and there are some nice ones. However, I don't understand why Solidworks has not made it possible to sketch on the side of an extruded cylinder and some other odd shapes without adding a new plane. I wish we could just click on the rounded side of the cylinder and sketch. This option should have been standard with cad software years ago, but as far as I know, no cad software has it. Solidworks is a leader in innovation, so I am asking them to please add this time saving option.
