Altitude deviation alarm / alert

Is there a way to set an alarm in SkyDemon for a predetermined altitude? Situation - I fly between 2 areas of controlled airspace with lower limits of 2000'. I usually maintain a 400' - 500' buffer but had a bit of a squeak yesterday in thermic conditions and lack of attention that got me to within 120' - Phew  😳. An alarm at 1700' could alert me well before I get close to the airspace. It's all down to me, I know but it is a feature I would use. Thanks, James.

Do you have the SD audio alerts connected to your radio/intercom/headset?
I do and find it invaluable when SD warns of "controlled airspace xx feet above".
The trigger appears to be when I start climbing, intentionally or unintentionally due to thermal activity.
I frequently fly between Southampton and Bournemouth where CAS is at 2000 ft. My aircraft is quite "light" so is affected by thermal activity.
I watch my altimeter carefully!
