BF6 Portal Map Making limitations

I loaded up the Godot Portal map editor full of excitement and ready to start recreating some classic BF2 maps to find out that you cant create a new map, you can't even edit Terrain on current maps. 

It feels like a waste of potential to not include this feature and to limit people to adding assets to current maps only.

Original BF titles included a full map editor and even Far Cry has a built in Map editor. I don't see why EA would want to limit the community when they advertised Portal as being able to create your own maps.

Please EA allow us create new maps and edit terrains and mix assets
