Kensai MagusPerfect Strike?

[Derek Dalton]

I am playing a Kensai Magus Monk Multiclass. I just reached fourth level magus granting me Perfect Strike. The ability states if I hit with my chosen Weapon in this case a 9 Ring Broadsword I spend an arcane point and do maximum damage. Pretty straight forward.
Here's the question I am a monk with Flurry and using Ki to make in this case three attacks. If I hit with all three using my broadsword would I be able to spend three Arcane points to make all three max damage hits?

If you like. It's not a swift action or something. Not really worth it unless you're doing just one combat/day, but it is possible.
