Which tool in A AS is used for mass creative upload?

The Ad creation wizard in Amazon Ad Server (AAS) is the designated tool for mass creative uploads. It streamlines the process of adding multiple creatives simultaneously, often supporting various formats and sizes in a single batch. This is crucial for campaigns with numerous ad variations. "Smart upload" is not a standard AAS feature for mass creative uploads; while AAS offers intelligent features, "Smart upload" isn't the specific name for this functionality. The "Attachment tool" is typically used for adding supplementary files to existing creatives or campaigns, not for the initial mass upload of creatives themselves.
