If you would like to make a workshop with only small changes from an already existing workshop, you may find it easier to duplicate the existing workshop than creating a new one from scratch. These instructions will help you to create a workshop that duplicates all the titles and settings of an existing workshop, which can then be tweaked and edited as needed.
Step One: Navigate to Create>Workshops from the sidepanel navigation menu.
Step Two: Select the Workshop that you'd like to duplicate by checking off the toggle next to the workshop name
Step Three: Click the Duplicate button and then, when prompted, press ok to confirm that you want to duplicate the workshop
Once the workshop is duplicated, you can open and edit the new duplicate.
