perhaps it helps when you import the pin assignments from the original development board design. In e.g. <NIOSDIR>\examples\verilog\niosII_cyclone_1c20\full_featured\ you'll find a .qsf file which contains all the pin assignments as 'set_location_assignment PIN_XX ...'. You can copy these lines into your own .qsf file and then label your pins to PROTO1_IO[] or PROTO2_IO[]
