Is there a way to search QRZ.com by IOTA reference? This would be very useful for IOTA hunters. For example if you were missing AS-004 you could search for stations that have their station on AS-004. Then you could see if you already have a QSO with one of them which has not been marked as AS-004 in your logbook. Alternatively, assuming your logbook has the facility, you could declare the stations that come up on QRZ.com as AS-004 in your logbook so that whenever they are spotted on the cluster they show up as a new IOTA for you even though the IOTA reference was not included in the cluster spot.
