Radio buttons/ checkboxes for admin back end product variations section

I wonder if someone can create a custom woocommerce plugin. It is about the variations on product page. If you have a lot of atributes is high time consuming to create every combination you need with specific conditions. Let’s have the next example:

I have a T-shirt avaiable with next atributes:

color: A, B, C, D, E, F (for some shirt are even 40 colours, so i pick only 6 for the sake of example)

size: XS, S, M, L, XL

The prices are the folowing:

price 1: color A in combination with any size
price 2: colors B, C, D in combinations with any size except XL
price 3: color F in combinations with any size except XS

At first glance you would say to create all combinations and delete the ones you do not need.

For some products with over 400 combinations is not an easy task, i guarantee it.

I need something like in the atached picture (sorry for my photoshop Skills).

I searched all over the net the last 2 weeks nothing found, and a lot of people asking for something like this.

I hope someone is going to do this. I am willing to pay/donate/give my soul/beg for it/marry the person who does this.

Thanks
