To duplicate an activity, go to your Activities page, check the box next to the activity you want, and click Copy in the Activity Menu.

A popup will appear where you can rename the activity. By default, it will auto-fill as:

[Original Activity Name] (Copy)

—but you can change it to whatever you like.

Below the name, you’ll see a dropdown to choose where the new copy should live. By default, it will place the activity in your top-level Home folder (the outermost breadcrumb). But you can use the dropdown to drill into any folder — even subfolders — and organize it exactly how you want.

Once you click Copy Activity, the duplicate is created instantly.
