LR Publisher plugin default watermark on thumbnails

Its been some years since I last looked at this issue and over the past couple of years, I have decided that as internet speeds and screen resolution has increased, I should increase the thumbnail size. All well and good.

Now, I find that the thumbnails are of sufficient quality that I want my watermark to appear on them as well. Not a problem, just uncheck the selection choice in the ‘Features’ tab in the LR publisher add-in when publishing a new album. Is there a way to change the default?
