In order to quickly copy and paste multiple elements to other pages, we have implemented the import objects functionality into the Pro Editor. You can use this feature to import elements from already existing projects, which can be very useful to recycle (parts of) your creations among different projects.
Go to the options menu in the top right of the editor. A list of option will appear, among which you will see the import objects option.
A popup window will appear, in which you will see several drop-down menus. First, select the project from which you would like to import an element. Then select the page and optionally the scene from which you would like to import. Now you can select your elements and import them by clicking the blue import button. These elements will then be positioned in the center of your canvas, ready for you to reposition and edit to suit your current project.
