Make non-variable attributes look like labels

Hello!
I’d be very thankful if someone could suggest any solution for this issue:

I’m creating a e-commerce web-site using Woocommerce and Shopkeeper premium theme. I use several attributes. What i need is to make non-variable attributes look as label/images (not as plain text) and to be displayed not in “additional information” field.

Exemple: (labels “З” and “Ми”)

What I’ve thought of:
1. Create a custom field (but Advanced custom fields plugin seems to be too complicated for me).
2. Use a plugin that a) makes non-variable attributes look beautiful, e.g. labels and b) moves them not in “additional information” field, but higher, next to variable attributes and add to cart button. But any plugin i’ve found so far seems to work only with variable attributes. Non-variable attributes are still displayed as text and in “additional information” field.
