Yandex.Metrica, how to add additional parameters to the goal that will be visible in analytics?

Question

JavaScript

Added a "JavaScript event" target after a successful form submission: But the fact is that this form was made using a plugin for the CMS. And it is used simultaneously on several different pages. Tell me, is there any possibility in the metric to add a custom parameter to the target, which would indicate the address of the page from which the form was submitted? I know that you can get the current URL like this:
ym(52036167, 'reachGoal', 'form-contact');
window.location.href

Answer 1

<script type="text/javascript">
    var goalParams =
    {
       url_page: window.location
    }
</script>

ym(52036167, 'reachGoal', 'form-contact', goalParams);
