Make the share folder screen and file request password screens PROFESSIONAL

My organization uses dropbox Business and it's extremely embarassing when I send file requests to clients OR when I send them a password protected shared folder. Instead of seeing our logo branded (or even dropbox's logo which only appears very small in the top left corner) and any indication of professionalism or security, all they see is the image of a dinosaur whispering in someone's ear (when a shared folder) OR my name and "drop some stuff here." I can't continue file sharing this way with clients and need to switch to using One Drive so my clients will finally take us seriously.
