Download File From URL
 

I have a hyperlink in my spreadsheet, a URL to a TIFF file.

When the user clicks the hyperlink, the download file dialog
appears--as it should, however it uses a generic file name
("File1.TIFF") and I'd like to default to a filename that's in another
column in the same spreadsheet, any ideas?

I've been searching all morning, is there some additional HTTP data I
could post to do this?
