In AEM Guides is there any pre processing workflow like post processing workflow

I have an requirement in AEM guides cloud when an asset uploads need to perform some update activity on metadata .
Earlier we hv Dam Update asset Workflow and there we can add any custom workflow model to achieve this goal .
Here in AEM cloud as this workflow not available hence without adding any custom workflow is there any OOTB preprocessing workflow to achieve this goal.

This issue we have resolved by creating a custom workflow and it will trigger on creation/upload and update of an asset in dam by using Launcher configuration .Thanks.

You can use an OSGi Event Listener/Sling Event Handler. You can listen for the asset creation/update event using a Sling Event Handler, and then programmatically update metadata.
