Can one customize the text size for a file folder in the directory tree

Can one customize the text size (and color) for a file folder name, and each sub file folder name, in the directory tree; and how many layers can the directory tree go??? The font size for 'Raw In' is say 24 and the font size for 'JPG' is say 12.......Just like one can do in microsoft word and excel.....

Raw In

You can change the font size, but only for the entire tree.

Labels can apply font color and font style (bold/italic) changes to individual folders, as well as re-color or replace individual folder icons. Labels cannot change font sizes or faces for individual folders.

What would it entail or require to have your coders programmers add this ability? It would greatly enhance a large many level directory tree....
