Custom Data label for Clustered Column chart

Hello Experts,

 I am using clustered column chart where I want to customize data label on this.

For ex. I have chart value for one bar as 98.5 then want to add x as suffix on this and show as "98.5X"

If we have some alternative custom data label option would be helpful because for now data labels are showing value fields value. if we get option like regex what we have in SSRS that will increase our design customization as well as more value to product and our dashboards.
