I had already complained about this issue before, as I am used to other apps where you can search for a point/address without having to add it to the route straight away or first have to laboriously turn it into a POI, which is actually undesirable.
Brian's answer showed me the way to the solution.
I activated the ‘Ask for waypoint name’ and ‘Place waypoint button’ options.
Now, when I search for a point, it is displayed on the map and a window appears at the top for naming this point as a waypoint. I click it away and now have the point I was looking for in front of me without it being added to the route. The ‘Place waypoint button’ option displays a destination marker.
If, after checking, I do want to add it to the route, I simply click on the Place waypoint button, the above-mentioned window reappears and I can name it and add it to the route.
For me, this is a really good way to do it.
