You’ll need to be a bit more specific than that.

 

Which pages do you want to add icons to? Where do you want to add the icons?


I want to do below change, 
1. to add additional icon for Survey window,(Active icon, Test survey icon,... ).

What I know is, by using which php files pages(source files) that icons are added.

Then can I know by using which php files, create survey URL?

Thanks.
