Order 'Complete' date? - does CSCart record this?

I've only just realised that CSCart doesn't seem to display the date an order was given the 'complete' status. This is something I was so sure would be in there I never even checked, but I can't find it.

We need this information to help with dispatch queries.

Am I missing something or is it not part of CS? I realise we can get CSCart to send emails to the 'order dept' when the status reaches complete and we could keep copies of those and search through them - but this isn't a very elegant solution for something seemingly so simple.
