User defined templates for health values per device

Currently there does not exist a straightforward way of templating certain health values for any specific device model. Values can be bulk edited using SQL but there should probably be some kind of user defined template which would match the device model using regex. That way the user could define some values that would be used as the default low and high limits for the sensor data for any current and new device if not defined otherwise. Modifying the yaml-files is probably not solution since that if not model specific. These values could then be overwritteng per device using the normal health settings tab if needed.
