Interactive connected map system

I was thinking, on the site you could have the ability to have an interactive map system that you can deploy your completed maps. A bit like World Anvil but just for maps.. For example….. Upload your world map from Inkarnate, Add markers on the map or pins. When you click on a pin it takes you to a kingdom map you also created on the site and that map allows you to add markers like cities within the kingdom and that marker takes you to a map of the city. and in the city map you can add markers that take you to battle maps. So a step system of layered maps from the world map all the way down through kingdoms on the world map to cities and other locations on the kingdom maps to eventually battle maps.. A good way to keep subs after they made all the maps they have made… Instead of going to world anvil
