Learndash groups content protection with tags

Currently, I use learndash to protect courses and memberpress to protect posts/pages tagged premium. Learndash provides the option to lock posts/pages with learndash groups. However, it only has the option to lock contents inside post editor by selecting individual courses/groups. How can I make learndash groups to protect posts/pages tagged premium so that I can deactivate memberpress and use only learndash?
