External sirens needed

We've installed our alarm today and you can't hear the siren very well at all outside of the house. As we have multiple ring cameras around the perimeter the option to have those sirens sound in additional to the internal one would be great. Id like to see the linked devices option for the alarm split into two sections, one to be for entry delay to have the option to trigger recording and sounds as it does now and then separately alarm sounding to have options for recording, lights and sirens. Shouldn't be too much of a leap from what's already there. Maybe a maximum external siren ring time to ensure that they only ring for 10 minutes so a false trigger wouldn't ring all day. In the UK people are used to all alarms having external sirens, so this is a big lose if moving to this alarm.
