if multiple speed/cadence sensors exist, can Fenix be set to select priority/active?

Admittedly this is probably not a common occurrence but I find it annoying the Fenix seems to give up when multiple speed/cadence sensors exist on an in indoor bike ride for example and will only select the sensor with ZERO and not the one actually active?

To be specific imagine a standalone speed sensor installed/active but then a combo speed/cadence sensor is installed for cadence.

The Fenix cannot use the cadence sensor by itself, it will only look at either the standalone speed sensor OR the speed/cadence combo sensor.

I want to override the zero output of the combo speed/cadence sensor for speed with the active speed sensor.

But the fenix refuses.
