Automatic siren triggering for Ring Stick Up Cam Outdoor

Dear community, I own a Ring Alarm Kit and 2 Stick Up Cams, installed outdoors. Can I automatically (!) trigger the siren of a Ring Stick Up Cams outdoor in case of motion detection? Has this been made available as a feature in the meantime? Or does the siren still has to be triggered manually in case of motion/danger? Thanks a lot for your reply, Christian
