Is there a way to upload a csv of invite codes to Membership2

Currently the Invite Codes addon to Membership2 does not enable bulk uploads like the previous version did. If you are running a business on this plugin like I am, this is a huge setback. Invite codes are a great way to keep your membership clean, avoid spammy or nasty members, etc. As it is, I would have to manually enter hundreds of codes in order to make this new version of the plugin useful to my business.

Since bulk uploads have been overlooked in Membership2, is there a way I can use phpMyAdmin to upload codes? What table?
