Sync latest email attachment with Android My college mess hall menu is shared as an attachment (.jpeg) on the same thread every week. The thread has no other content except for this.
For convenience, I'd like to access it quickly from my Android mobile. I don't want to keep it as a starred conversation and interrupt my urgent emails.

Is there a way to sync the file (i.e the latest attachment on the thread) so that I can have one click access to it? Maybe sync it to google drive so I can use widget or rename it to current_mess_menu.jpg and save it in a Dropbox folder so I can do the same? Open to other alternatives as well.
Assuming you use the Gmail app, it always downloads the attachment if you're on WiFi AFAIK.
