Simpler than what?
What I showed was illustrative of the concept, not the
utmost fewest syntax. Names can be given to common
combinations, for example. (This could be in the
form of functions, or a built-in configuration names.)
You are not selling hierarchies, but shortcut names.
My approach has WAY more possible combos than a tree.
Make a little grid and see for yourself.
