No Conditional Formatting Drop Down?

this is ok for the slicer background but there is no option of conditional formatting for Slicer Values. 

For example, my dropdown slicer has 10 product types, out of which 7 products type were sold last day... I want to highlight values color or background or make it bold or italic to let my users know what productions were sold last day so he/she can directly go to those products instead of checking all 10 products one by one to know the sales. 

How do we achieve this on drop down slicer? Any workaround?

Here basically I am trying to conditional format the values but no option availabe.
