Mark all email as unread with one click

[dtone314]

It is becoming more and more tiresome to delete all the spam and other emails I have already read via webmail (the messages are still on the server, so they download to my phone).

It would be SO helpful to mark all emails as read with one click of an icon, or something of the sort. I, myself, have no knowledge of how to do this, but maybe one of you is inclined enough to give it a shot? Just an idea.
