Adding Option to Paste URL in the Upload New Form Dialogue

What high-level problem are you trying to solve?
Trying to reduce time during development, particularly on poor internet connections.

When creating a new form in a project on ODK Central, instead of just having an upload button, could we have a text field to paste a URL of an XLS file also? ONA allows this and I've found it quite helpful. I now exclusively use Google Sheets to make forms, iterate, test, etc. This would save the steps of having to export/download an XLSX file from my google sheet, then re-upload onto ODK Central on a bad internet connection.

EDIT: Downloading/Re-Uploading is particularly annoying when starting a new form because each time it fails a validation check, users have to change that issue, redownload, and re-upload.

Any ideas on how ODK could help you solve it?
Not sure on the code, but I imagine this is fairly simple as I know the Central API supports this.

Users could paste publicly shared XLSX URLS like:

https://docs.google.com/spreadsheets/d/e/here_is_my_long_google_sheet_id/pub?output=xlsx

Upload any helpful links, sketches, and videos.
This is the exact dialogue I'm talking about. Adding a text field in another box underneath the Drop a file here would seem the most ideal UI wise.
