Fog of War in turn based game

[historix69]

I noticed in the gameplay video of Civ6 that the Fog of War immediately changes when a unit is moved, e.g. if a unit sees tiles 1-7 from position 1 and moves to position 2 where it sees tiles 7-14, the tiles 1-6 vanish immediately and tiles 8-14 are revealed. Since it is the players turn, nobody can change the tiles 1-6 and the player has full knowledge of these tiles but they are now hidden in the fog of war. I would appreciate it if the known tiles would be somehow visible until the end of turn.
