Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Sorry, its like trying to read German, and I don’t speak German. The images are not clear, as far as I can tell, I have tried exactly this, it didn’t work and I wasn’t able to return my map to it’s original state.
