Hi Ikaroweb,

Thanks for contacting us here.

Unfortunately, that is impossible with our plugin. Since the variation selector on the Sticky bar might be in conflict with the main selector of the main product if you're using external interfaces not from WooCommerce such as swatches, radio buttons, etc. So it's better that the sticky bar only reflects the choice in the main product, but not embedding the selector right on that.

Best regards.
