Multiple Sales Tax Rates for a single invoice

Hello,

Our city launched an additional tax where some of our items are now taxed at 7.9% while other items on the same invoice are taxed at 8.4% as they include a .5% food and beverage tax.  I can't for the life of me figure out how to build this so some items are taxed at rate 1 and some at rate 2 (or rate 1 plus the additional .5%).

Any help is appreciated.
