Add a condition to check against a specific date. Using format functions you've access to various PHP date functionality. Example as follows.
[cb:parse function="time"][cb:date format="Y-m-d" /][/cb:parse] Less Than [cb:parse function="time"]2019-08-01[/cb:parse]
The above should cause the auto action to stop working after 2019-08-01. Beyond that no there are no plans to implement Publish Up and Publish Down usages.
