Need your help on I-485 Ref

Hi, everybody. I helped many poeple here. My previous is nickane futon. Now i need your help witn my I-485 ref. My attorney responded my wife's and my daughter's I-485 REF, but he put them together in one package. I don't know if it is OK. So far, online information show that they recieved my daughter's Ref, but my wife's is not updated yet until now. so i am worrying about it. Anybody had same situation? Can we use one package to send several REF?
