How to add an existing variation to a product How to add an existing variation to a product?
When I create a product the form forces me to create a new variation, but I also want to add an existing one to the same product.
Turns out I know what you're talking about Nikolaos, and you're in luck! There's a checkbox!

Here's an animated gif that walks you through the steps that I've outlined below:




Navigate to your Content Types
Manage Fields on your Product Display (you may have more than one of these)
Locate the Product Reference or Product Variations Field, click "Edit"
Scroll to the middle and locate the checkbox "Allow users to add existing variations"
...
Profit!
