Tax question for mix drinks

In The Netherlands we have two kind of taxes:

Alcohol with a percentage of 0,5 or more: 21%
Non-alcoholic drinks or lower then 0,5%: 6%

Now what I want to achieve is 1 button for a mix like Bacardi + Cola that adds 1 Rum and 1 coke to the ticket.

So the coke must be charged with 6% tax, and the Rum with 21% tax.

Is this possible?

Looked at a lot of combo thing, but order tag and so on isn’t working for this.
