How do I get an EX9 layer output pin on my module?

I want to tidy up my patches by saving chunks of them off as patches and then dragging them back in as modules. Even though I make sure they have an EX9 output pin in the patch I don’t know how to get it show up when I drop it in as a module.

getting the terms straight: the patch we see has one input pin and three output pins.

you should find the answer to your question here: subpatches#parameters

Thanks Joreg, all I had to do was middle mouse click on the I/O box…
