yes but it does depend on what makes them variations such as size and colour with how you want to list them.

There are 3 ways to do this. You can create a new product and then add the variations in. You could do this via an upload or use the create variations wizard.

Once you have created the parent product, you can then drag the other products in by using the asins or eans as your child products.

You will also just need to check that your particular category for each asin accepts variations and they are in the same category as well as having the same brand name.
