With custom made fonts that are gathered online (and not yet available though Adobe fonts as of yet, or are specialized and likely won't come to Adobe fonts ever) it's really nice that we're able to upload fonts onto CC. However, I've noticed that I don't have a way to attach the license to the font. Luckily I'm working for myself and I have a system to keep all of these licenses in check whenever I'm publishing something using 3rd party media.
But if I was working on a team project or if I was constantly jumping from computer to computer, it would be a horrific situation in which I would be liable for stealing a creator's work without giving them the appropriate credit.
Obviously I'm over exaggerating a bit, but it would be a time saver (and potentially money saver) if I could upload the license file I was already given to the same library I'm uploading these fonts to.
