Bigger icons for several selected units on bottom panel?

Hi, im lookig for a way to increase the size of the icons of the units on the command panel (when i select more than 1) because i think that they are so small, even with 125HUD, (im thinking for something similar to aoc icons size). i tried to write on the commanpanel JSONfile in the part of “Clipped Area”, and others, but doesn’t works. Im completly begginer in modding so i want to know if this is posible or needs more advanced knowledge. I JUST WANT TO INCREASE THE ICONS, NOT MAKE +60 SELECTED UNITS BOXES.
