I'm broadcasting my heart rate and I want to set up a custom data screen on my fenix 7, but I can't figure out how. Note that I'm not running an activity on my watch while broadcasting - I'm simply sending the HR to another device. The default display shows heart rate with a very small time of day at the bottom. If I bring up my normal watch face when broadcasting the HR, it will always revert to the broadcast HR screen within a minute or two.
