Hi @Loris Bonotto ,
Not sure if you could use any Sharepoint location or Onedrive folder as path for the updates.
But as a workaround, we could sync SharePoint files with local computer. Thus you could link to this folder in the computer.
To sync SharePoint files with your computer, you could refer to this article: https://support.microsoft.com/en-us/office/sync-sharepoint-and-teams-files-with-your-computer-6de9ede8-5b6e-4503-80b2-6190f3354a88
