We’re still evaluating how to implement something like this.
Our idea is to be able to add multiple files at once but there’s a small challenge: adding documents to SharePoint requires metadata to be added as well (Title, additional columns, etc.).
We may implement bulk file upload by creating the new items with the same metadata. For example, all documents’ title will be the documents’ names.
This is still an idea in progress and we’d appreciate any feedback regarding this.
