Leave the map in the same place when importing when the maps are sorted by date added

[Glebsin]

Sometimes I have to open downloaded map in the stable client, but when opening map I forget that it will open in Lazer, thereby the map goes up to the top when maps sorted by date added, and there is no way to return map to the place where it was.
I propose to give the user 2 options - replacing map with a new add date or replacing map and keeping old add date
