You can’t. That’s OK because you don’t need to. There’s no impact from having multiple results files uploaded to a meet, only the most recent one is used.
If the results file import says “results awaiting "swimtopia support review"”, uploading the same results file won’t help.
In any other case, uploading a new results file will replace the existing results completely. Uploading the same file again won’t have any visible impact unless you upload the same file multiple times in a row in rapid succession. This can cause duplicate results for your swimmers. If that occurs, simply upload the correct results again, once.
