I am using Adobe Marketing cloud Debugger. In the SiteCatalyst image, I saw a field call "current URL". It is the URL with passed in parameters. I am wondering is this field saved in adobe server? If so, how to access it?
I am afraid, you will not be able to recover campaign reporting.
For the future, I would advise to implement a custom variable for URLs that would allow you to build segments based on fragments in URLs (e.g. URL contains cid= OR URL contains cid=email_xyz). Then these segments can be used for building advanced calculated (derived) metrics.
