Condition for Cost of Item

Hello,

We specialise in portable bar hire, to dispense kegs of beer and cider.

I am hoping to set up WooCommerce so that customers can select the type of beer they want & their preferred bar. The total cost would then be determined by the bar + keg. Essentially, two items. Though, I want to add them as one item, so customers cannot add a keg without a bar.

Would it be possible to introduce two attributes, with a cost increase based upon the attribute (i.e. bar) chosen?

Hope that makes sense.

Thanks in advance!

Any ideas or suggestions would be appreciated.
