I'm fairly new to using the pipe network features and knew this issue was approaching.
I know how to edit the pipe part properties to change a pipe from the size indicated in my parts list to another common size for the particular material specified. However, I've run into a non-standard size that is not in the dropdown menu, how can I add another size to the list?
Basically, I need a 1.5" on the list in the attached screep cap.
