Tracking Call Clicks via Adobe Launch

Hi,

I'd like to track phone number clicks on a website where the numbers are in HTML tel: tag

<a href="tel:1-800-262-562529">Call us</a>

How can I do this in Adobe Launch. I see there is a CSS selector option in Adobe Launch > Core > Click > CSS rules but is there not a Click option where I can put a Regex, if link click URL matches "tel:" THEN fire rule?

Thanks.
