Too Many pointers Too Close Together

I do a lot of sightseeing meaning that I fly from an airport, add points of interest, and ultimately go to the destination airport having flown over a point, or points of interest view them from a low altitude. This works fine in areas where there a few sights and a distance between. However when flying over London when a pick a point I have to fly through a large cluster of pointers that do not allow me to see parts of London that are on the way through the flight plan. I am using the flight simulator to create a flight plan. There is just too much clutter of pointers.
I would guess that these point of interest have their data in a table somewhere on the C drive of my computer.
Would it be possible for me to modify the table to show only the pointers I am interested to add to my flight plan?
I have some considerable experience in computing and could take safeguards to insure data integrity.

yes they can be annoying but you can turn them off or on, hope this helps

Where do I do that - can’t find the setting. Does that mean all are off, if so, how does that affect flight planning?
