Hi, John.
I appreciate your question and the desire to customize it for your use, but we do not provide customizations, per our Scope of Support / Terms.
It sounds like you might have an existing custom code snippet in place already that you’re looking to tweak a bit. Is this correct? If yes, please share that entire snippet so we could take a look, as well as an annotated screenshot demonstrating what you have now and what you’d like it to be, along with a link to view this in action at your site.
Whether for now or in the future, I’ll also share our documentation and list of known customizers.
