shortcut to Edit palette?

P2020 has a new palette when you open Advanced Brush Control (ABC ) panel...see jpg image herein.

It is call Edit and shows to check on Shape or Media palettes.

I thought I'd like to have that palette handy outside of ABC, but could not find a shortcut to it, nor ability to add it to a custom palette.
Is it possible to do so? or is it only available in ABC?
