Preferred font file naming convention?

I'm trying to import a bunch of font files (185 of them) all at once and it's not going well. 😅

- Some of the fonts have no name after import—they're just called "regular", "bold", etc.

- A lot of fonts are assigned the wrong name.

- It looks like two or three fonts were imported over and over again & just given different names.

I was going to try renaming the files so that they all follow a grafika-friendly format to see if that helps, but what format would that be?

Thanks!
