Additional Information with TWebFileUpload

Is there any possibility to send information when uploading a file with TWebFileUpload?
The UpdateHandler in the demo provides ARequestInfo, but I have no idea, how to put information into the request befor uploading.

At this moment such functionality is not built-in in TWebFileUpload.

This will require an extension of the component. We'll investigate & consider this.

Thanks, Bruno! (for answering and considering)

I'll try to do a workaround with storing data in a db and matching it to the uploaded file - already have an idea for this.
But I would definitely prefer to deliver the information in one turn with the file.
