My Ultimaker S3 printer doesn't have soft PLA as a material selection. It would be nice to update the library. Is that possible? Otherwise, I need to learn how to successfully create a need entry. Can anyone help with that?

Our college just bought a new Ultimaker S3 and we're trying to get set up. We're running into a few newbie problems, and wonder if there are any Ultimaker veterans who might want to make a few bucks getting us started on the right track?
