Anbody had same situation on I-485 REF

My attorney responded to 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?
