Way to display XMP Relative Altitude in Info pane?

[BluePhilG]

Any way to show XMP entries that are not in the existing drop down lists for the Info customisation?

Using a DJI Drone, Relative Altitude shows up in 2 places in the Properties Panel:

Under XMP, there's a 'dji-drone' dropdown that lists 'RelativeAltitude' and under ExifTools, under the XMP dropdown section, there is 'Relative Altitude'.

I've tried adding {XMP:Relative Altitude} and {XMP:RelativeAltitude} and a few other options without success.

Is this possible?

Ah, ok, thank you for confirming.
This is a feature I'd def be happy to pay for
