How does one update their application on file? More specifically, I'd like to upload a current resume, but I don't see a way to delete the one already on file. Anyone know of a way to do so, or do they just stack up on top of each other?

Also, it appears there's no way to go back to the flight time portion of the app once it is submitted (no way to update TT), correct?

(This is in regards to their request in the email I got to periodically update my resume/app.)
