You could try to use macros, but you need to know the name of the skill it replaces. I use one on my MCH to automate chainsaw. Mch exaple would be
/micon “Drill Shot”
/merror off
/ac “Chain Saw”
/ac “Drill Shot”
puts the keyboard icon as drill, executes chainsaw, and if chainsaw is on cd executes drill instead, and has no error message because they are turned off with merror.
