You can click for the solo product and click “Add a variant product” to add variants. You can select a property to create the variant and then click “Add”. After which, you can enter the equivalent product id and the product name.
Enter the values for the variant property. For example, if color and size is your variant property, you can enter the values for color and size. Once you enter the property values, you can click “Create Product Variant”.
