Now that Vocera Staff Assignment allows up to eight assignments per room/bed, in cases where only one or two people are assigned to a room per shift, it can be used to assign staff over a number of days.  In this case, the same staff may well be assigned to the same room for a given shift on consecutive days, however, VSA doesn't allow this.  I think the usefulness of being able to enter a staff name more than once would outweigh the risk of duplicate errors and would increase the value of Staff Assignment as a whole.
