There are several words you can add to the subject line that help you do more complex processing. They are:
Example Subject: recap 6/29
Time of day
Example Subject: results aft 6/29
Example Subject: recap section YY 6/29
To revise results, just submit them again. You do not need any special keyword to revised results.
Example Subject: results 6/29
It doesn't matter if you use upper, lower, or mixed case. Also, certain words in the subject line are just thrown away, like the days of the week and dashes. So,
Example Subject: Results - Monday 6/29
will process just fine.
