Doesn't look like that feature exists in the app. You should be able to see this on your computer tho. If create date is important to you, you should include the create date in the filename. I do that all the time as a habit. Then if I revise the doc and need to maintain revision control I add -r1, -r2, etc., to the end of the filename, after the create date. I know some people who like to add revision dates instead of -r1.
