su_members short code

Is there a way to have su_members short code just not show anything if the user is not logged in (like su_guests when they are)?

I tried message=””, however the horizontal bars still show.

I used to use Simple Access Control short code which are inline allowing me to change words/sentences within paragraphs based on login status. I removed it figuring that your plugin would have this covered. I don’t want to have multiple plugins for short code usage, please if your su_guests/su_members doesn’t already do this please implement.
