Not sure if this is a first or not , but yesterday , I managed to catch two transits of ISS across the sun on consecutive orbits......from one location.
Last year I managed two consecutive orbit transits , but had to re locate between passes . This time I simply stayed where I was , and waited for the station to "come back round".

Great fun , but, on what was probaly the hottest day of the year here , not recommended
