You may need to duplicate a collection - for recurring project types like a monthly checklist, or a yearly finance report.
Open the collection settings by clicking on the collection name when it’s open. Select "Clone collection" from the activities menu.
This will open a dialogue where you can choose to rename your collection (if you want) and select a workspace to send the new collection to.
If you are working on a mobile device, click on the name of the opened collection and click on "Settings".
You will find several export options in the "Actions" section in the settings. Click "Clone Collection" to duplicate the collection.
Give the duplicate a name and select the workspace to which you want it should be added.
