Arm Away vs Arm Stay

I am using Smart Things with my Alarm Panel Pro. There is a siren wired to it and all works good. I get text messages for any change. I would like the siren to blast when in ‘Armed Stay’ but not when in ‘Armed Away’ mode. Currently the siren goes during a breech in either mode. Is this possible?
Thanks

Smart Things doesn’t have different response settings for the two security modes so that isn’t possible yet.
