Currently, we support dynamic SubIDs to use in your target URLs. In the not too distant future, we'll include it in the UI to make it a bit more clear.

You can add the {url} parameter to any URL and it'll get replaced with the full page URL on click.

So, for example, the link would look something like this:
https://linktosomewhere.com/a-product/?affiliate_id=abc123&label={url}
