Hi Tim,
Unfortunately that is not supported at present.
The third party (and now unsupported) plugin Event Rocket does offer a means of doing this and you could potentially still use that, or use it as the basis of your own approach if it doesn’t quite fit your needs.
Another alternative – which we use on our own demo site – is simply using one of the many available redirect plugins to shift users instantly to the main events page, whenever they land on the homepage.
Beyond those options, it would really involve some custom development to implement this in the short term.
Remember also you can always vote for this on our UserVoice page 🙂
