In the 'Structure' tab, it is possible to copy entire steps, including all fields that are within the selected step. More information on how to do this can be found in our online guide: Copying steps.
When copying steps, you have the ability to choose where in the study to copy to. It is possible to 'cross-copy' steps between study, reports, and surveys.
Phases cannot be copied directly, but it is possible to duplicate study structures by exporting the phase and importing it again in your study.
