Start CDs on Pots, Mecha Blast rocket etc... during combat once used?

I noticed that if you have a pot or something like the mecha blast rocket macroed for use in a sequence the CD for them will not start until after you have left combat.

Anyone know if there is a way to trigger the CD for multi-use during a long fight?

Mecha-Blast Rocket shares a CD with pots. You can only one or the other once per combat session and they only go on CD after combat ends.

how do you include this in the premacro stage? i can not seem to get it to work…

/use Commander’s Draenic Agility Potion

is it supposed to be entered as: “/use Commander’s Draenic Agility Potion”?
