PDF Highlighting - Change Default Opacity?

Is there a way to change the default settings for highlighting text within DTTG? Specifically, I prefer the least opacity setting for the yellow highlight. Also, it would be great to change the default colors (and even add one color to the defaults). (Note: I use a single color scheme for highlighting in Kindle and iBooks and would like to extend that scheme to PDF highlights in DTTG.)

Thank you!

It’s currently not possible to edit label or highlight colors in DEVONthink To Go (and adding the functionality requires interface additions that would have to be carefully considered). Perhaps in a future version.
