Uploading files in a folder with Web screen

One of our customers has a requirement of uploading files in a certain folder one-by-one with the Web screen.

What is the best approach to achieve it?

The thing that immediately comes to my mind is:
Step #1: Get the result of PowerShell's "ls -name" command as one big Region with using General DOS Console.
Step #2: Get filenames from the Region with StringUtils component or something, and store them into List.
Step #3: Execute the Automation to each filename with using ListLoop component.

But it looks like a complicated implementation. Any idea on a better way?
