I think it would be great to see this ability feature in fieldmaps as that's the platform we use widely.
We use the these point to create an elevation profile in our electrical line design software (which only accepts points in a csv with x,y,z parameters)
This feature is already available in QuickCapture

Currently our workflow involves streaming in Fieldmaps. The output of which is a polyline.
We then use the Vertex to feature tool to create points.
It would be good capture these directly in the first place.
