Short answer: No! ...
And if you are out of combat, didnt measure the time, because it doesnt change anything, its about 20 or 30 seconds, then the eclypse resets.
AND you even cant cancel the buff ... so, BalanceDruids are, to my knowledge, simply fucked (but not in a consent nice way) for optimal Multiboxing. I was myself thinking about it and found no solution with the toolkit the macrosystem and isboxer provides. Even if you monitor with TMW the buffs, you will get very fast out of sync with the buffalteration. So just alternate starfire and wrath is the "best" i came up with
