May be a global current strength setting in device assignments existed with previous Quartus versions. But as far as I know, it doesn't, now. You can set rather easily a current strength for all pins in the Pin Planner, I think, but you can also apply a single line assignment for all pins in the Assignment Editor or enter it as a tcl command.

P.S.: I see, that a global "*" assignment doesn't work as with previous Quartus versions. So setting current strength in the Pin Planner to all pins or groups of pins seems to be the best way now.
