I am using PMPro to allow memberships on my site.
When creating a membership in pmpro there is the possibility to hide a membership from checkout and disable people to sign up for it.
Due to my set up I have several of these sort of memberships. Basically I want to manually assign a membership to a person and not make it possible that someone buys it. However, it is impossible to add such a membership to a course. It does not show up and it gets deleted from a course when you disable signups.
Could you tell me how to add memberships that are disabled for signups to a course?
