Well, the spreadsheets were made during pre-COVID times and the general practice was to have the interview right after the test (on the same day) and decision made within a couple of days. It never accounted for COVID, online test and a myriad of interventions brought about by the pandemic. This is akin to the "in process ECAS" tab but ECAS is not available to online applicants so it's hard to tell what "in process" even mean. In your case, I think you can just add it to the Notes tab that you had an interview after test since that is an exception rather than the norm.
