This is a shameless grab from Elevation Profile Widget - Reference polygon featu... - Esri Community by @JavierML .
They'd like to know which soils they'd find along an elevation profile. Considering that there's a soil polygon feature availaible, it should be possible to represent this soil information with different colours within the elevation profile.

Maybe this idea is already possible, but I couldn't mange to do it. The only idea I had is convert the polygon borders into lines so the are intersected along the profile (as you can do with other lines), but the process is tedious, unreliable and not aesthetically pleasing.
I'd like to see this functionality in ArcGIS Pro, as well. For example, one of my users wanted something similar to show land ownership along the length of a trail.
