Impact theme more metafield data

[PBoss]

Hello!

I'm looking for a way to add more metafield data to my products. My webshop is selling phone cases, so it's crucial that the customer can select the phone model and case color/type.

I created the color part as in the tutorial for metafields from here:

But need to add phone model to the product page too. But the 'Product varations' block no longer available, since it's there already. I tried add multiple with comma, but it's not worked.

Thank you for the help!
