How can we make each exported form have a unique name?

We have our form automatically export to a subfolder in our Dropbox account. When we do this, the files that export all have the title of the form. Unfortunately, Dropbox assumes its the same file and overrides other files with that same name. Is there a way to append the date just to the file that is exported? We're able to do so if we have it create a unique folder each time, but that's not what we want to do.

Thanks!

Unfortunately, it's not possible to set a unique name to the files sent to the Dropbox folder, you can only set up a unique name to the sub-folder created under the main one and avoid files being overwritten.
