We are upgrading Pega 4 to Pega 7. Quite lot of CSS styles are custom coded in Text files. When I inspect an element, I see the CSS for the element in the browser. For ex.,

element.style { } .groupTitleBarIconSPANExpanded {     display: block;     background-image: none;     width: 30px;     background-repeat: no-repeat;     background-position: 6px 0px; }

Is there a way to quickly identify which text file, the above CSS is picked up from? For ex., the above code comes from user_work_form.css text file. To find that, I had to do manual search in the designer studio looking for this class groupTitleBarIconSPANExpanded. I am looking for an easy way to find the information.
