Would it be possible to automate play store updates/add a automated dev channel?

[Nintonito]

Thought occurred to me while browsing the play store dashboard features.  Isn't it possible to enable and set timed weekly updates,  that could be hooked into buildbot in some way?  That way the play store listing can get reliable updates easily,  meaning there would no longer be an influx of users on a horribly outdated version.  Even better, the updates could be posted to a seperate listing for dev builds,  while the current listing is saved for "release snapshots".
