Add zones's away/frost protection set temp as comfort level temperature

I use a common heating profile used to control two zones; an underfloor zone and a radiator zone. Which is very convenient.

Each zone permits setting an "away" or "frost protection" temperature, but this is only used if you switch the zone to standby.

I would like to be able to set the temperature in the heating profile to use whatever the zone's configured away/standby/frost protection temperature is instead of setting a specific temperature in the schedule.

Rationale: both the zones are heated by a gas boiler, and the building only has periodic use during the week. During cold periods I would like the underfloor zone to activate at a frost protection temperature that is a few degrees above the frost protection level of the radiators, because dumping heat into the large concrete floor is a better strategy than heating the air.

Suggestion: This can be an app only feature. Add a frost icon into the temperature wheel just below the 5.0° entry, or a special one tap icon.
