Scheduling: Publish changes on a specific date and time
With this, you can schedule the publication of content such as products, categories, layouts, or promotional banners in advance. This allows you to automate time-sensitive campaigns, reduce manual effort, and ensure content goes live exactly when needed.

If you are owner of a Evolve license or higher, you can use Shopwares Dynamic Access feature as workaround, which allows to use Rules from the Rulebuilder.
https://docs.shopware.com/de/shopware-6-de/erweiterungen/dynamicaccessThis allows you to define that products, categories, and CMS Elements are only shown in the storefront when the connected rule is successful. And with the Rulebuilder, you can build rules that are only successful in a specific timeframe or even only for designated customer groups. :)
