To duplicate a product Customizer, go to the Customizers tab on your Maker account. You can find it here. Click the down arrow found on the right-hand side of the screen. This will bring a pop-up menu where you can select Clone Customizer.
Simply provide a unique Product ID and the duplicate Customizer will be generated.
To create variations of a published product under the same Customizer, select ‘Add a New Product.’ Each new product should be a different and unique combination of the options available from that Customizer.
These methods can allow you to significantly speed up the process of adding your products.
