Add "Upload G-Code" to Feature Unlock#748

Hello! Love the feature unlock system that you have. I would love if you could add the ability to upload g-code as a feature that we could provide by user rather than just by user group. We work with alot of first time 3D printers, or people that print at other spaces, but don’t know the particulars of our system. This is an area were uploading g-code can be a problem. However, we want to give certain members that have talked with us, or demonstrated proficency to be able to do this, while keeping newer members on the simply print slicer. It would also be great if slicing profiles could be added to features! for example, being able to unlock advanced slicing parameters to individuals rather than user groups. Thanks!
