Hello, I have two questions regarding optional components for pcb assembly: 1\. Trying to\, for instance\, to define which 0 Ohm resistors \(or other optional componets\) to not be assembled on the PCB\. How can I do that? There does not seem to be such a feature\. 2\. Is it possible to have 5 PCB assembled with one set of BOM\, and another 10 PCB \(same physical PCB design\) with another set of BOM\, thus creating two stuffing options? Thanks for the help.
