[Membership 2 Pro] Membership 2 - Unprotect post excerpts - protect full post

When a visitor goes to a blog or the article post section, they see a list of the articles along with a relatively short excerpt that is an intro to the article's content. Is there a way for Membership or anything else you are aware of that will open the list of article excerpt to guests so they can see the brief summaries of each article? But, if they click to see the full article, they receive the block message instructing them to sign up or sign in.

This is a client's request. So, any help you can provide is very much appreciated.
