Updating tags without changing file time-stamp?

Has this been discussed yet?
I would like to update tags without changing the file's time-stamp but cannot find a setting to do so.
Thanks!

EDIT: OK, I found a "work-around" for this problem. I've created a new column called "Created" that displays the file's created date and time. But this doesn't effect the "Modified" date stamp of the file itself, just displays the created date in the mp3Tag window.

Tools -> Options -> Tags -> Preserve file modification time ...

Thanks mate! They hid it there, eh? :blush:
