Using a schematics symbol with bus

Hi all,

I need to implement a 4-bit counter (74161) in my schematics, I found a Verilog example but I'm unable to properly wire the symbol because it uses bus for inputs and outputs.Specifically I need to label the outputs in a certain way (because they are outputs from the CPLD and they must be labeled as H1, H2, H2, H4) while the four input must be tied to GROUND.How can I obtain this?

Here's the piece of code :

module ttl_74161 #(parameter WIDTH = 4, DELAY_RISE = 0, DELAY_FALL = 0)
(
  input Clear_bar,
  input Load_bar,
  input ENT,
  input ENP,
  input [WIDTH-1:0] D,
  input Clk,
  output RCO,
  output [WIDTH-1:0] Q
);

//------------------------------------------------//
wire RCO_current;
reg [WIDTH-1:0] Q_current;
wire [WIDTH-1:0] Q_next;

assign Q_next = Q_current + 1;

always @(posedge Clk or negedge Clear_bar)
begin
  if (!Clear_bar)
  begin
    Q_current <= {WIDTH{1'b0}};
  end
  else
  begin
    if (!Load_bar)
    begin
      Q_current <= D;
    end

    if (Load_bar && ENT && ENP)
    begin
      Q_current <= Q_next;
    end
  end
end

// output
assign RCO_current = ENT && (&Q_current);

//------------------------------------------------//

assign #(DELAY_RISE, DELAY_FALL) RCO = RCO_current;
assign #(DELAY_RISE, DELAY_FALL) Q = Q_current;

endmodule

Thanks in advance.
