I'm using the blog add-on purchased from marketplace and I'd like to have a user group called "Bloggers" who can log in and add new posts, but not edit anything else. I can create the group and assign users to it, but is it possible to give them permission in such way that they can only access blog (and file manager) in dashboard? I know how to use advanced permissions, but how can I add them to pages on dashboard?

Thanks.
