Yes - you can absolutely use a team member’s individual role design as a basis for yours so you don’t have to start from scratch.
Simply duplicate their role by following these steps:
Step 1: Navigate to your Team Design dashboard by clicking on the Teams icon on the blue left-hand Navigate Bar and then clicking on the hyperlink to your team.
Step 2: Click on the role you wish to duplicate.
Step 3: On the right-hand Editing Panel, click on the 'Duplicate' tab and it will make a direct copy (including the hours + tags).
Step 4: Assign yourself to the new role and edit/add/delete activities to reflect how you spend your time and how you feel about it.
