Ability queue?

[Warchild_Zek]

Is there a way to set it so I can just queue up the next ability without having to spam the button? I see that it does that for about half a second, but I'd really like to just hit the button once.

You can queue any ability tied to the GCD .5 seconds prior to the GCD being refreshed, but that's about all you can do.
