Thank you @AlixVezina for another good solution suggestion.
I have actually tried the new Edit widget in Experience builder, but the feedback from testers were that they did not understand the words "add feature", or add "geo-objekt" as it says in the norwegian version, which most of our users will see.
But the Edit widget solution comes close to what we are looking for, as does Survey 123 also, we now need to continue testing and exploring.
We have also tried configuring the Crowdsource reporter, but the fixed field structure is also a challenge.
Thanks again!
