If a dynamic object's updated position is not correct, due to incorrect estimation of speed or because the real target moved differently than predicted, the dynamic object may be moved to the new position and will continue its travels from there. For example, if the lead rider for a bicycle public service event passed a radio operator staffed checkpoint earlier than predicted, the dynamic object for that rider can be moved to that point, either by manually dragging it across the map to the new location, or using the "Move to Object" popup menu choice. This menu choice pops up a dialog window to allow the user to select the name of a location on the map where the object should be moved. Such a location can be an APRS station (identified by callsign-SSID) or local or remote APRS object (specified by object name, and grouped into local, remote, or specific APRS "milepost" objects), or the name of a "special" node added to the regular OpenStreetMap data (currently, only the MS150CueTranslator and BMMapGenerator utilities provided with the YAAC source code distribution can create a special.nodes file).
