Even better answer… Right Click the component. Should get a context menu with the fourth option being edit component. From edit component, there will be a second context menu with the fifth option being unit with a right arrow. Clicking on this reveals a drop down list with the different options for that homogenous package. Click the box next to the option that you would prefer. For example, if the component lists A, and you want D, just right click->edit component->unit->box next to D. The component will immediately change to UxD. Happy layout!!!
