Indexed Colors and Swatch Palettes

[Evans Design Works]

Is there a way to have saved swatch palettes have a descending number for color placement? For example... If you wanted (0) color to stay zero and you had say five different shades of grey being 1-5 in order. When you swap the colors around they are numbered 1 through 5 just the swatches move and change position while the numerical order stays the same. I hope this makes sense... I attached an altered screenshot to help visualize.

Thank you in advance.
