Connecting nodes to a bus, Howto?

I have a 32bit wide PIO bus from a NIOS block and would like to connect parts of this bus to other single nodes.

All of this is done in Quartus II at schematic level.

Have a look at the attached image.

I would like to connect ArithmeticControl[0] to the clk_en and ArithmeticControl[1] to the aclr pins of the altfp_mul3 block.

How should I do this?

Do I name the clk_en node as ArithmeticControl[0] and aclr node as ArithmeticControl[1] or is there a different method

Thank you
