Hi @ssawaikar ,
To do this, you would need to overlay the existing report creating wizard in AEM.
As you can notice in your URL, the component you are looking for is present in dam/gui/content/reports...
By this way, you can overlay many things in AEM.
I have gone ahead and looked at this and the exact file which you would need to overlay is :
/libs/dam/gui/coral/components/admin/reports/createreportwizard/selectreportcard/selectreportcard.jsp
This is responsible for rendering all the different options present in the createreportwizard.
You would need to add a new button(div) in this JSP and add your custom logic/class to it.
