Task Viewer to use Growl

[Ash]

I like to see when QS is doing something so i do not get annoyed by a
momentary slowness... so i have turned ON "show task viewer" in the
prefs... as i also use Growl.. is there any way to get QS to use growl
if it is available on a system to present me with a growl notification
rather than the "task viewer" window.
