Permanently dismiss WPMUDEV Dashboard notification in our sites

I'd like to be able to permanently disable these notices.

EDIT: This isn't related to the Dashboard Feeds plugin but since it's mandatory that these Support posts be applied to a plugin, that's what we have.. Also since we can't add an attachment to Feedback (request already posted), I can't post an image here, only the link. Sorry.
