Box API Development Inquiries / Suggestions

I don't see a category for suggestions to improve Box API, but one that I have is the ability to change email notification settings for specific users on a folder. I can do this with sync by accessing the API using "as-user," but I do not see a field in the Info object that correlates with email notification settings. I don't imagine that this can be terribly difficult, seeing as it is a similar operation to turning on sync. From what I've read on other forum posts, this feature is currently not available; if it is, please steer me in the right direction.
