Importing paid fonts – Fonteer Review

Why is there no way to bulk import from the files app? If I want to import, for example, Sophia Pro I have to do this once for each of the sixteen sub-fonts: open files, navigate to font, select one (selecting all of them does not work), press share, find then select the app, then select the collection. After 16 of those I end up with a single font installed.
