In reports of type Email Link Performance, every unique URL, including the Query String, is given its own line under the E-mail name.
We always add a unique ID in the QS (linked to the lead ID) for all outgoing mail. (Note: this is the only way to get Munchkin to track web pages by Marketo Lead, so please don't bother recommending not adding this token.)
As a result, Email Link Performance reports are close to useless for us: imagine seeing 1000 individual lines with no added value, each with one click and one lead (it's actually even worse than that as we have multiple clickable URLs per e-mail).
Is there any way to get a report with the exact same data, only rolled-up (grouped) by http://host/path, regardless of Query String?
