STHM - Intrusion Detected - is immediate notification but delayed Siren/lights possible?

Is it possible to setup the STHM in the new ST App so that a push notification is sent immediately that an intrusion is detected, but the siren and strobes etc. don’t go off for a short period so we can reset the alarm if we have tripped it accidentally … e.g. one of the kids opens the back door in the evening?
