Multi boxer question

[Cowsfly]

Hello I'm just getting into multi boxing and had a question for you guys.

Im using keyclone and was wanting to make a hot bar of my boxe's spells with there correct icons i found all the spell icon information, is there a way to make a macro with a spell icon from another class? Say have is ae nuke be the correct icon for his ae nuke, i know i can drag icons from my spell window into macros but i dont have the icons on my main toon that i want to use.

I know i can load the icons into custome raid ui's i have done that but i was just wondering if this can be done.
