Changing Generic Icons

[A.J.5EA8]

Hi everyone,

How can I change these generic icons to something simple? Like letters. I'd like to make the first one "A." The second one "AR." And so on. Is there any way I could change that? I've attempted addToolBar method in Javascript and it hasn't worked for me. Is there anything else Javascript related that would work?

Any help would be greatly appreciated.

It's not possible to change the generic icons, sorry

It is possible to set the icons of toolbar items added using JS, but it's quite complicated.
