No I really dont know how. Try scanning for your cooldown time as it is normally, upgrade your skill a few times and see if the value changes, then you can scan again and see if you only have 1 address left, otherwise keep upgrading until you can no more and hope to god your cooldown changed and you only have 1 address left.
Freeze it and change it just to see if it works. I don't guarantee this method at all because Ive never tried it. Just a brainstorm :) But, it is something to get you started.
