Commerce: Stock & Price Adjustments + Custom Fileds

[Cyberg Studio AS]

Hi there,

 I'm setting up some commission products under Commerce. I added a main product "animation" and wanted to use the "custom fields" to add "extra options" for the customer to choose from -or- add to the main product before checkout.

Now, the part on adding "custom fields" and linking them to the main product under "Stock & Price Adjustments" wasn't a problem. I ticked off the "Use different stock levels and prices depending on custom field values" and added the price to each "extra option" and saved it. So when I tried it the price adjusted as intended (see pics) "No Extras = Animation 1200 // Gore +300 = Animation 1200 + Gore 300 =1500) but the PROBLEM is....

...that I can only use the "select" and/or "radio" alternatives under "Field Type" to make IPB happy, and not the "checkbox set" to make ME happy. You see, I want my customers to make multiple choices and not "single" choices and that I can't figure out how to do, IF there is such an  option? 

I have tried different approaches but with no luck. Is there an workaround here or do I have to make multiply products and the "Association" option?

Every option would need to be its own field. 
But that only works well with two or three options, because you will get a matrix of every option combined with every other option and you would have to set up each price.
