how to show Pneumatic diagram with options

[Nathan Gardner]

I have only done a few and it has been many years since I have created any kind of PIDs. I have a product I need to create a PID for. This diagram will always have the CO2 source, and from there, it may have a CO2 backup and or N2 source. If there's an N2 source, they could be an additional N2 backup. How should I show this in one diagram with line types?
