Is there any way to show custom images for submenus in aeon mq 7 ?

As title says, I have been searching for couple weeks on n off for a way to make custom images for submenus but I can not find any information anywhere on this paticualr question.
I hope someone here has an idea. I tried couple other forums but had no reply after almost two weeks..

I understand what images it is showing but wonder if it is possible to make the submenus emselves have seperate images each.

Thank you for your time and any possible help in the future
