Having a build not immediately go live?

[blendogames]

Hi, I was wondering if there's a process for uploading a build, and have it be publicly 'hidden' until I tell it to go live.

The use case for this would be for an already-released game that has some sort of planned update. Ideally, I would like to be able to:

• Upload the build ahead of time.
• When the release date/time arrives, I'd like to be able to make the 'hidden' build instantly become publicly visible.

The purpose behind this would primarily to be a safety net:

• To have some time to verify the build's download, to be able to make sure the download is good.
• On the day of release, to streamline/expedite things by being able to instantly release by clicking a button.

(I noticed there's a checkbox for "Hide this file and prevent it from being downloaded", but I wasn't entirely sure if there was a way to upload a build with this checkbox activated by default.)
