Good afternoon Spatial Node,
I have developed a tool free to use and download that makes downloading elevation data, specifically the Shuttle Radar Topography Mission Data directly within ArcGIS Pro.
The tool consists of two parts: 1. The One Degree Spatial Cell Layer, 2. The tool itself.
Simply import the One Degree Cell layer directly into your map and make your selection, while inside of the toolbox ensure that the "use selection" option is blue. Finally log in to your account (a link is provided in tool to make an account) and download the requested SRTM.
Thanks very much for your time and I hope this tool is helpful to you. There is more documentation that goes in greater depth within the GITHUB link below.
