There is no need to create a new task and enter same parameters all over again. 'Save as copy' function lets you copy a selected task while giving you the freedom to change some task details.
Must-know about this feature
When copying a task, the new task will have the same parameters as the initial one but they won't be linked.
Copy a task
Click on a task
This will open the pop-up window.
Click 'Save as copy' on the right
A new task will appear under the initial one.
Change desired parameters
You can change the name, project, utilization, custom data fields etc. Save as a copy is a good function for you if you schedule the same tasks for different projects. You don't need it to recur, you just need the same thing to happen for a different project.

Click on save once you are done.
The two tasks are not linked. Changing details of the copied task will not affect the initial one.
