I have done this by dividing the current amplitude window value of the current grain for the current sample by the sum amplitude window value of all grains.
I then multiply the current sample value of the current grain by this value if the sum amplitude window value of all grains is greater than your max amplitude value ( say 1.0 ). Otherwise, I just use the window value as normal.
