I was just thinking about this feature; it'd be nice to implement sometime.
In the meantime, Nuclear, I suppose you could make an additional download for the beta for people who want to opt in, but it'd just be available to everybody.
That is not an option, as we dont want anyone to be able to download these versions yet, we are planning to release an open beta later on, but we want this specific channel to serve as a close beta, more prone to bugs, internal use only.
