Smoke/CO listener with separate smoke and CO alarm

I just set up a ring alarm system with a smoke/CO listener mounted next to both a smoke and a CO alarm. Can I set up the one smoke/CO listener to monitor both the smoke and the CO alarm? If So, how? Is there a way to list the alarm types that it's listening for? I thought I had set it up for both, but when I viewed the certificate, it reported that I only have professional monitoring for "...Burglary, Panic, CO.". I set it up for the smoke alarm first, then I repeated the setup step for the CO alarm, but it seems like the CO alarm setting overwrote the smoke alam settings. Did I do something wrong, or does this listener only store settings for one device?
