MATLAB: How to rearrange subsystem block ports

inputoutputrearrangesimmechanicssimulink

I would like to rearrange the input ports of my subsystem block (attached image) from:
  • Servo3_cmd
  • Servo2_cmd
  • Sevo1_cmd
  • MachEnv_setup
to:
  • Servo3_cmd
  • Servo2_cmd
  • MachEnv_setup
  • Servo1_cmd
Is rearranging the input/output ports of a simulink block possible?
Thank you!
NB : If anyone is interested, I found a better way to rearrange the ports. You go into the subsystem PMIO block and you set the port number and port position (Left/Right), which rearranges the inputs 🙂

Use this code to get the different ports then use delete_line and add_line to arrange them
b=get_param('untitled/yoursubsystem','PortConnectivity')
n=numel(b) % number of blocks connected to block1;
out={};
for k=1:n
  s=get(b(k).SrcBlock);  % search for source blocks
  if ~isempty(s)
      out(end+1,1)={'Source'}
      out{end,2}=s.BlockType;
      out{end,3}=s.Name
 end
end
