I have a "Review Survey Submission" feature layer and an "External Map Points" feature layer.
I want to edit an existing point from "Review Survey Submission" (edit the Status field) as well as copy its values and paste them into a new "External Map Points" point. In other words, I want to edit both layers at the same time in separate open popups or panes.
As far as I can tell, this can't be done in the Map Viewer. Could this functionality be added? I don't want to use the attribute table by switching back and forth between layers to copy/paste the values.
Here's a screenshot of what it would look like in Experience Builder with two separate Edit widgets. Experience Builder might work for this - TBD. But I want to submit this idea for Map Viewer as well, since it would be good to have multiple app options.
