I don't believe you can today, but this sounds like a fine enhancement request.
will you log it in MOS as Enhancement Request, or do you want me to do this?
It will mean more coming from you.
And the Forums aren't a bypass method around My Oracle Support. I probably do too much here in terms of answering questions around bugs, but I'd rather err on the side of helping you.
I will use MOS to log this as an EnhancmentRequest.
Unfortunately I did so for 3 trivial things already in march this year and none of them made it into 4.0.3. Even though one of them has been classified as a bug.
4.0.3 had only a small handful of bug fixes and 2 basic feature changes, in order to support a few new products we're launching or have launched.
The next release, 4.1, will have many, many bug fixes.
You can ask your MOS rep for updates on those 3 previous bugs to see what their status is.
