Currently the attach documents function on the bots uploads to a public link on Amazon's servers. For our business use this would be a breach of data security. The attach function provides a simple and user friendly way of getting documents to us and an easy way to integrate with our existing processes; if there was an option to add integration with Box (our current file storage) then we could better utilise this function. Alternatively, if attachments were uploaded to another secure file sharing service we could integrate with this too.
