Update Preview when using different Raw Import Tool

Hi,

is there any way to update the preview of my pictures after editing them using RawTherapee or Digikam via the new Raw Import Tool settings ?
I see the adjusted inside Digikams Image Editor after closing the “external” editor but not in the Thumbnail overview or anything else. This would be quite useful, because otherwise it is quite hard to tell which pics are already adjusted.

Thanks for any hint.
