Ah yes, it was when I was adding the DSI output endpoints. I also ended

Would there be any benefit to labelling the ports for convenience?
Probably not enough, and it would only be there as a shorthand to be
able to still get to the endpoint which would still need it's own label
I think... so I think this is fine as is anyway.
