Display Tertiary Attribute capability on tile

I think its great to be able to display Secondary attributes in the lower right corner of the tile, but I would like to also display a Tertiary attribute in the other corner.

My current use case is for the Awair Air Monitor tile:

Hero: Awair score (91)
Secondary attribute (lower left): Temp (76F)
Tertiary attribute (lower right): CarbonDioxide (578)
