Hi, I have a client that raises cavys (guinnea pigs) and the experts suggest when introducing new ones to the exsisting group, they put vanilla or a touch of peppermint on their noses, it distracts the smell long enough to give the new addition a chance to smell like the others. You may try this. I know when I add my new ones, after they have been with the others for the day, they all will smell the same, but the other idea is great if you can't get them to adjust quickly.
