Main product and option product as one product in cart?

-- HikaShop version -- : 5.1.0
-- Joomla version -- : 5.1.1

Dear Hika Team,

I have the following situation.

On my site I sell events with drinks and snacks at an all-in price of €35.00.

The drinks are the main product (€30.00 with 21% tax)
The snacks are an option product (€5.00 with a tax rate of 9%)

I want them as one product displayed. I already tweaked the product detail page with succes (img1) but the option product is still showing in the cart (img2).
Is it possible to hide the option product in the cart so that in the cart it also looks like one product?

Thanks in advance

Edit: One more question.
Customers can check out as a guest, but there is only an email field. Is it also possible to just add a name field? Address fields are not necessary.
