Would like to be able restrict text messages to a group to only users currently at the site (much like you can do with calls and broadcasts today). We attempted to have some emergency calls delivered to the vocera (via nurse call intigration), these calls are pointed at the OB group at the site. In this department (OB) they share some staff with a second site - in turn some staff are in both sites OB groups in Vocera. We would like to be able to limit that message so that users not working in the OB that is having the "code blue"  do not get the urgent message.
