Elevation and Navigation fields on Ultra activity

I discovered I can't add any Elevation data fields to a screen on the Ultra activity profile.

Is this a bug or a feature? Am I missing something?

Specifically I would like the simple Elevation field to easily see my current elevation. 

I know you can get similar data by using Climbpro, but I would need a course set and it seems strange that this whole category of data fields seems to be restricted on the Ultra activity type (considering elevation is very relevant in mountainous trail ultras).
