Hi Steve,

Creating your own is pretty easy.  
I'd convert the the regular 21step into Lab first.  The values will be wrong
but you'll have all the labels and the layout.  Then redo the actual steps.
Start with a new gradient (dither off), then posterize part of it to 21steps.

This is an interesting exercise, you'll see the difference in curve shape with
the different gray spaces.
