I figured out how to add 'Custom Properties' to parts from the help files, but it says nothing about adding 'Configuration Specific' properties. Plus the AddCustomInfo function is apparently superseded (but it does still work). Not sure what the difference is.
I can find a similar question asked but the code is in C# and I couldn't make sense of it.
Anyone know how I can add 'Configuration Specific' properties to a specific configuration?
