Thank you for posting this idea. I submitted an ESRI case, in which an enhancement request was generated. Here is the correspondence:
I completely understand and agree that this should be a core functionality especially since it is available in ArcGIS Pro and Map Viewer Classic. I'll be sure to note that with our internal team as well. I'm glad we were able to get the enhancement logged and definitely encourage giving a "Kudos" to the following Esri Community Ideas post to help bring additional attention to the request by our internal teams.
