@franciscraven "shift" + "Left Click" does work with power cells, with a caveat: It only works with cells of the same type. That is, you can only upgrade all single/double uranium to double/quad uranium, single/double plutonium to double/quad plutonium, single/double thorium to double/quad thorium, etc. Cheers!
