Which of the following is NOT a capability related to creating projects in Xero?

Merging projects is not a capability currently offered within Xero's project management features. Xero allows users to create new projects, edit existing projects, and add tasks to them, which are fundamental functions for managing projects effectively. Creating projects for new customers enables businesses to track time and expenses specifically associated with those clients, while editing allows for adjustments as project details change. Adding tasks to projects is essential for breaking down the work and managing it efficiently. However, the ability to merge projects does not exist, reflecting a design choice in Xero's project management framework that focuses on clear project organization without overlap.
