P: Additional levels in Preset Hierarchy

I really need at least one level more regarding Presets, so it easier to organize them.

I.e

My Presets

      Color

           ...

           ...

      B&W

          ...

          ...

Your Presets

----

Or even better

           Landscape

                ... 

           Portrait

                ...

      B&W

          Landscape

               ---

          Portrait
