Remove a schedule from an article - unschedule

I have created a draft of a published article and scheduled the draft to be published on July 1st. My product manager has asked me not to publish it. I can’t find any way to remove the schedule. The only option is to push the publish date out as far as possible OR publish the draft and then use the version options to return to the prior version. Shouldn’t there be an “unschedule” option?
