I am currently working on a shield for an Arduino Due board. The Due board has a couple pins which are connected to the 5V on the Arduino board. I wish to define these pins on my board as having the same net name and being connected externally (off-board). This way I could use the 5V from the closest source available. I have now realized this as adding an inner layer and connected the pins using this layer. This works for now but it may lead to confusion later.
I want to ask what is the best practice in this case?
Is there maybe a setting which I do not know about to define signals which are externally connected?
