P: Add Custom Brush Presets

I was (and still am, I guess) so, so excited about the launch of the new CC. However, I was extremely disappointed to find that there is no local adjustments folder to add custom brush presets. I chatted with an Adobe Support rep and they said that it "may be added in the future" and to post on here.

I cannot believe that I have to post on here asking for Adobe to add a main chunk of my workflow back into Lightroom. I can't be the only one whose LR workflow is affected by the lack of this capability.
