[Plugin: Add to Any Bookmark Button] Exclude categories?

I found the <!--nosharesave--> tag information, but I’m wondering if it’s possible to exclude the button from posts in a specific category altogether, say ‘Asides’, ‘Tweets’, and/or ‘Don’t feel like sharing’?

It could be much easier than trying to remember to add the <!--nosharesave--> tag on every post that belongs in those categories.

Thanks for reading, and for the plugin. 🙂
