Change the name of objects(button) from Cancel to Loading

[SK28]

Hi,

We have developed 20+ KPI's using buttons & CSS script to beautify the  back ground and font size alignment and all

But the problem here is as there are more than 40 button used in this KPI sheet, while applying the CSS it is showing as "CANCEL" to the each button, Can we represent them as "LOADING" , rather than as "CANCEL"

Please find the screenshot for better understanding

Any help on this, Can this be achieved???
