Variant move notation problem

In variant when there are 2 or more pieces of the same type can move to the same square but only one of them do, the move is still notated as if only one piece of that type can move to that square.

Example: in this game

https://www.chess.com/variants/4-player-chess/game/52129829

blue's 8th move is notated as Nb8 even when there are 2 blue knights that can move to b8, which lead to a lack of information when there are 2 different moves that can be notated as Nb8.

In normal chess we don't see that problem. 

If you move the mouse to the notation you'll see Na10-b8, and if you download the png4 file then you have Na10-Nb8

Or you can just see what happen on the board...

You can also turn in enhanced notation in settings, that gives you color coded and extra specific information about moves
