lol Thank you anyway.
I called NS Office of Immigration and they suggested to wait till we receive application numbers to send any updates/changes to them.
The process, as I understand, is:
1. They are only receiving the applications and haven't opened any of them yet.
2. Once they start opening, they will check whether all supporting documents are included. At this point, we will be receiving application numbers, I believe. They do not have any ETA for this.
3. Then comes the validation part. This is when we could provide updates/changes.
Hope this helps others in the same boat.
This seems to be a common mistake that many people did including myself. Can't we send them a courier with a letter or an updated NSNP 100 form immediately rather than waiting ?
