Change color of only certain part of text in a data label

[Ashkelon]

After creating a pie chart, I wanted to change part of the text in the data labels to another color. However, when I tried to highlight some parts of the text, it only allows me to highlight the entire text instead of only part of it. This means that I could only change the color of the entire text, not part of it. Not sure if there is a solution for this since nothing came up when I googled about it.
