Once you've finished the first variation of a design containing Dynamic Design Elements, you'll then be able to automatically generate variations of the design with a single click.
After you've created the first variation in your design, open the 'More' Option in the Design Module.
After opening the 'More' toggle, you'll be able to access the 'Generate' option. Clicking Generate will automatically create designs using your initial design as a template for the new designs.
Designs created by Automated Variations are completely self contained, and can be edited, previewed and exported like any other Flexitive design.
