This should be possible - you would need to append the existing data using either ArcGIS Pro or the ArcGIS Item Details page. The form would also need to be set to have the Inbox enabled.
Perhaps I misunderstood what you are asking - I was thinking you had an external data source in the office with previous data compatible with the survey.
If you are asking about pre-filling a form in the office and then going to the field to complete it, you can do that by making use of the Drafts folder - close the form and save to Drafts.
so if i use the draft folder, then once on the filed it will update the point coordinate where the survey took place to reflect it correctly in the Survey123 website?
