Restrict sub-directories

Is it possible to restrict sub-directories using groups?

Example:

I’ve restricted a page that has a permalink of https://mysite.com/members/ to the “members_only” group.

Is there a way to restrict any permalink with /members/* to the “members_only” group? My problem is other functions in my web application might create /members/a_username/activity and I need to restrict everything in /members/

Thank you.
