Exposure warning in thumnail view?

Hi,

Is there a way to enable Exposure Warnings in thumbnail view (in the browser), similar to the focus mask? I find it very useful to work only in Browser mode, i.e. with Viewer off, when sorting and rating, and having Exposure Warning enables would be great. Since Focus Mask works on thumbnails I'm thinking there no reason why it shouldn't be possible to show Exposure Warnings as well?

Cheers,
Andreas
