Browser Tooltips EXIF MakerNotes

[Harribo]

Hi
In browser view when I go with my mouse over a photo I can see tooltips.
In Tools->Options->Browser (tab Browser) you can customize these tooltips.
Ok that is fantastic.
But...when I choose the EXIF tab under the photo I can see a "MakerNotes" section containing also fields like WhiteBalance,ImageQuality etc..
My guestion is...how do I add these fields to the customizable tooltips?
When I press the INSERT button at the options mentioned above, I dont see these fields??

Hope 1 has a clever suggestion:)
