Call now tagging from a Keap landing page

Is there an ad on available to allow Keap to tag a call now opt-in? I’m looking to have a form opt-in and a Call Now opt-in on my landing page, and currently, it looks as though I am only able to tag the form opt-in, not the Call Now. TYIA

How is the ‘call now’ getting generated? If it were by an IS/Keap form then you’d be able to tag them so I’m guessing there is something else you’re gathering that with?
