two questions and a problem regarding POIs:

I have two questions and a problem regarding POIs:
Question 1:
After successfully searching for an address, is it possible to create the option to either add this point to the route or save it as a POI?

Currently, you can only add the found point to the route.

Question 2:
When creating POIs, I sometimes see a yellow emblem to the right of the POI icon.

What does this emblem mean?

Issue:
I noticed that it's easy to move POIs in the app unintentionally. They then remain in their new location (= wrong location).

Is there a special setting in the app for this (POIs can only be moved with permission)?

I want to cycle the Ruhr Valley Cycle Route. Drinking water stations are listed with addresses on their website, so I need a way to search for and create a POI by address.
