Front-end uploading a csv file to modify database

Hello guys, I’ve been using Bubble for 10 months now, and I’ve set up a form page for the clients to request recordings of their classes. I’ve created another page to download the data and I want to know if there’s a way to upload a file as a front-end user and instead of adding the data as new info, to modify existing data.

Hey there, did you ever figure this out?
