Change simulink port location of signal after dragging block into "Create Subsystem"

Often times when I create a subsystem from a group of Simulink blocks, the inport and outports have the signals entering into the top.

I cannot find a menu entry to change these ports so the signal enters from the side, like normal. The only solution I have found is deleting the block and putting in a new inport/outport.

Is there a way to change this characteristic? It isn't a lot of work but it can add up (deleting the port tends to change all my port numbering and I have to reconnect signals outside the subsystem.

It's the same block; you just have to rotate it and resize it to make it look like a "fresh" block.

You can right-click the block and use the context menu to rotate and resize blocks.

Ok, thanks. So between rotating and resizing it's about the same amount of work as deleting, inserting a new port, and reconnecting.

Yeah, it is, but as you said it won't mess up your numbering.

What I usually do is use the shortcuts for rotating (Ctrl+R or Ctrl+Shift+R) and then select all the "messed up" ports, select a "good" one, and use the "match sizes" option, or whatever it's called. Makes things look better.
