it's very frustrating add fonts one by one
Only if it’s a repeated task. Maybe consider adding all the fonts you need and save the file as a template. Hence, it becomes starting point with all the work accomplished only with a double click.
Thanks for the request! This actually bothers me too (especially dealing with different weights) but we somehow didn't have it in our tracker. I've added this to the list.
great news! I think this would be a great time saving feature
