multi variation selection option with a fixed price

[stepheshadbol0]

Hi,

Im wanting to list some new items in a different way and Im not sure if such an option exists

In essence I want to offer a product containing 10 options at a fixed price of £20 and for the customer to be able to pick which ones they want

So the customer would be able to select

Selection A, 26 options, customer selects eg Ash veneer

Selection B, 26 options, customer selects eg Oak veneer
Selection C, 26 options, customer selects eg Maple veneer

upto selection J (10 selections)

At which point they would then be able to complete the purchase


Im not looking for options inbetween as we have those types of listings already, for the  type of product im thinking of listing the total has to be min £20 to make it viable 

Any guidance would be greatly appreciated!

Thank you!
