Tricky, it's 10500 miles away :-)

Not really, you wait until they place it, you grab it, log it into your oops cache with a 'visit' or full 'drop & retrieve', then log it back into the cache it is currently sitting in. If you want, mention in the logs you are correcting mileage. USE THE PROPER DATES.
Once they log it dropped, you have to move quickly so that it won't get picked up while you are working your magic.
ETA: the bolded/underlined is important.
Thanks - all done - really useful tip.
