Best way to share your game with the press before release

Hi everyone!

I'm wrapping up my Gear VR game which I plan to release by November. I haven't submitted the game for review yet to the store (as it is not complete) but it has already been covered by the press (based on my teaser trailer and screenshots). Is there a way to share my latest beta of the game with the press without using the 'beta channel users'? Keys would be ideal really, but keys are only available once your game has been approved, and ready for release, which may be too late. You see, the press doesn't always respond to emails (even when they feature/post about your game), and asking them for their oculus account emails in order to allow them to play the beta has been really tricky. It would be a lot easier if I could send them keys...

Has anyone had this problem before? Or have people been waiting for the game to be released before sending keys to the press?

Thanks for your help :)
