Hi,
You can setup Cubase so that it will not ask you, of you want to resample and it will do it automatically. But even then the resampled filled will end up in the Project/Audio folder.
You can set it up that the files will not be resampled, but then you change the skins and this is probably more wanted.
Therefore I would recommend to use a 3rd party tool to batch resample all your source samples on the network drive.
