When can/must defaults be added?

Hi,
I am in the fortunate position of having completed my IVA and the vast majority of my credit file being cleared (after the 6 year point) at the end of this month. However, there are one or two entries which show a default date long after what they should be. I know that a default date cannot be added after the acceptance of the IVA, but I also believe that the two remaining accounts would have defaulted earlier than that (at the end of March, the same as the others).
Obviously I would like my credit file to look nice and sparkly as early as possible, so I plan to write to these two companies with the IVA evidence to show that the dates need to be changed, but can i get them to put the date back even earlier? Are the companies obliged to put a default on straight away or can they hold off for a few months? I know i'll probably be p***ing in the wind trying to get it changed to earlier than the acceptance of the IVA, but any ideas on when they could/should have added the defaults and what I could use to prove it was earlier? I definitely know when everything defaulted because it was when my wife became extremely ill and our world pretty much fell apart.
Any thoughts would be welcome. Thank you.

The default date can be up to 6 months after the date of the initial breach/default of payment.
