Which Smartsheet feature allows customization of templates?

The "Template Gallery" is the feature in Smartsheet that allows users to customize templates. This gallery provides a collection of pre-built templates that can serve as a starting point for various project management needs, such as tracking tasks, managing budgets, or planning events. Users can select any template from the gallery and then modify it to suit their specific requirements, whether that involves changing the layout, adding or removing columns, or modifying formulas. The customization capabilities enable users to adapt the templates for their unique workflows and project parameters, enhancing efficiency and streamlining processes.

The other options, while beneficial in their respective functions, do not focus on template customization. The Attachment Manager deals with document management, the Automation Hub is for setting up automated processes, and the Collaboration Center focuses on team collaboration and communication. None of these functionalities directly relate to the modification or customization of templates as the Template Gallery does.
