Multiple buff crystals : Star Wars Galaxies Discussions

I have an question about usage of more than 1 buff crystal lets say the Retalliation crystal.
When u use one and it wears of then u have to wait a big time to use the same crystal again.
But what if u got lets say 5 if the retalliation crystals can u use the other without waiting time?

(i got 3 of them still <pending> and its a shame to waste one on trying if knowlegde is here )

if you use one, they all will go on the recharge
