[Membership 2 Pro] Protecting a group

Hi,
I've created groups of content in Upfront which I would like to protect with Membership 2. I Know I can use the shortcode [ms-protect-content id="membership-id"][/ms-protect-content] to protect content within these shortcodes, but I can't figure out how to get a group of content protected.
The reason I want this is because I would like to hide certain content for certain users.

I'm looking forward to your reply.

Julius
