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.
