3D Polyline Using Lat, Lon, Altitude MSL (Feature Request)

[seizler]

New Feature

It would be great to have the ability to create a 3D polyline using latitude, longitude, and altitude (MSL). This would let us display flight tracks in 3D, making it easier to visualize paths with elevation changes, like when tracking flights or other altitude-related data.

Is there any way to do this currently?

Why

Being able to see flight paths in 3D gives a clearer view of altitude changes and how they affect the route. It's especially useful for aviation and tracking any data where altitude matters.
