Analog Voltage Telemetry in QGC?

I’m running a flight test that requires real-time telemetry of analog voltages from the Pixhawk v1. Specifically, I’m installing an angle of attack vane and a wing strain sensor.

What is a good way to modify PX4 / QGC to telemeter two or three analog measurements so that they can be viewed in the QGC Analyze widget? I’m ok with inelegant solutions, as this is for a near-term need (next week).

It does not look like there’s a MAVLINK message to communicate analog values, so is the easiest solution for now just to insert the measurements into some other message? I don’t need all the actuator control fields, for example.

Is there an existing build where someone has already made this change?
