I suggest a bit of software that - in my opinion - should be part of your standard Flight Sim setup. It is called Little Navmap, and you can read all about it here. It will change the way you use Flight Sim.
The developer is on the forum every day it seems, and is available to answer any question you may have. Plus, a lot of us here on the forum use the software for flight planning and during flight because it is so doggone great!
I think you will find everything you are looking for - and more - if you give it a try.
Happy Landings!
