I have been playing with different macros and am currently using one where I basically mark a target and use shield lob on said target. I also added the line to change the macro icon which is where my question comes in:

I can no longer tell if I am in range for a shield lob or not, based off the icon (numbers are white, no matter how far away I am). Is there any way to get that functionality back?

While I'm at it, has anyone come up with a good way to mark multiple targets in a single macro?
