Each charging member in a group identifies a docking connection. Each charging member, responsive to identifying the docking connection, transmits information to other charging members in the group and receives information transmitted from another charging member in the group. Each charging member generates a list using the information transmitted to the group and received from the group. Each charging member also includes a ranking component for filtering, sorting, and ranking entries in the list according to a predefined selection filter and/or ranking filter. Each entry in the list is associated with a charging member with a docking connection and in the group. Each charging member determines based on a predefined indication filter that an entry in the list that is associated with the charging member is ranked at a predefined position in the list and provides an indication.
