Can I get some help with Maps and locations?

Hi

My Phone: Lumia 930 with WP 8.1

Q1- I want add a location to Here Maps by langitude and altitude cordinate. How to Ican do it? Is there a way or app that do it?

Q2: Is there an App that track my GPS locations and display tracked way and quickly suport bookmarking locations?

Thanks

When in Here Map have you tried entering coordinate in the search box?
Here maps support bookmark current location. Tracing your way, not sure. Here drive I think support saving a preferred route. Maybe you could use that.
