WPMUDEV membership account api limits

How do I increase my limit for the number of sites I have the dashboard plugin and updates active on? There was never a limit on the plugins / sites when I was a premium member before... I can understand the reason for implementing such a limit, but how do I turn the auto-installer and auto-updates off for sites I'm done working on so I can build the next ones, without disrupting the sites I've already built? What happens when I sell a site to somebody else now? You should have a feature in the dashboard to click a button for transferring ownership of a site, so that it will activate a trial membership with it's own api access to entice the new owners to purchase a membership, while locking in my affiliate ID for the commission....

Anyways, the main question is how do I request or purchase a higher limit than 20 sites, as this limit is no good for my needs...
Thanks!
