Custom flow runs with file upload option

Dear Prefect team,

Inspired by this, this and this, I would like to know about the possibility of launching custom flow runs with a file uploaded from the user machine as an argument.

In my use case, we have customer-facing colleagues that would love to plug a CSV file on a workflow and launch it without having to first upload it to S3 and having to indicate the URL as an argument.

Is this something already possible or on the roadmap?

We have the exact same use-case. We would love to know any solutions to this.
