Updating attendee information

We are hosting a Zoom Event for an internal corporate event for roughly 1,000 people that work at the same organization. We have uploaded the name and email addresses of everyone approved to attend but would like to add information to each person's profile (such as job title, date they joined the company, etc.) via an import list.

Is it possible to amend/update information for the people we have already pre-registered?

Thanks,
