Woocommerce: Connect two variable products in the one procurement process -- 2

I need is: Connect two variable products in the one procurement process When first product is main-product and second is sub-product. So, After that customer will complete to choose variation in the main-product, he will pass to the sub-product and then comes to the Card (purchasing process). The product price that will appear in all steps of the process it is total price of the sum of two products (selected variations) main and sub. Actually I have one product with 2 main groups of variation (when I tried to create this product under one variable product with very big numbers of variations the result was not user friendly) Its will be great if in variable product will added a new option "Group" or "Bundle", where I will can create "Name" for the "Group" and add picture (with "WooCommerce Variation Swatches and Photos"), will can sort these "Group" (like I can sort attributes and it terms). In the Product page, Groups will appear in tabs and under all tab will appear group attributes and terms. When customer will click on the tab, the main pictures will change according to the selected terms of the Group. Other way - tabs can be appear in different pages , then customer will have button "Next" or "Step No".... Important! I use: WooCommerce Quickview | WooCommerce Variation Swatches and Photos | WooCommerce Tab Manager | WooThumbs - Multiple Images per Variation [login to view URL] Images for example:
