Modifying the "Heading 2" default Text Callout data graphic

[RandolRoy]

I am using the "Heading 2" text callout for my data graphics. I would like to modify it to add Hyperlinks. Is there an easy way to duplicate the "Heading 2" (or any other) default text callouts? I've looked in the Stencil, the Drawing Explorer, the Data Graphics Configure and Advanced Data Graphics option, but I am not able to find a way to edit/duplicate it.

I believe I just found my own answer, so I will post it here. I found it by turning on Drawing Explorer under Developer tab AFTER I had already used the data graphic I wanted to copy in my current drawing. I was looking for "Heading 2" BEFORE I had used it on one of my shapes. @RandolRoy
