Thanks, yeah that is what I have ended up spending my while evening doing
The thing is I don't see how you can check what you originally submitted and I know for a fact there are going to be some discrepancies between what I originally submitted and what I am submitting now. There are just too many trips that I don't have in my current passport or have email receipts for the flights. I will just have to submit what I can and hope for the best.
I do have most of my USA ones covered 100% accurately, there were just loads of small trips around the EU which are not captured in the passport so difficult to get exact dates
