When I enter a hyperlink into a WCA mailing and link to a WCA landing page the link is "transformed" by WCA meaning some URL parameters are appended in order for the target page to be personalized to the recipient opening the link.

These parameters consist of the 4 following attributes: pMailingID, spUserID, spJobID and spReportId

For 3 of these 4 attributes corresponding placeholders exist in WCA:

* spMailingID: %%MAILING_ID%%
* spUserID: %%RECIPIENT_ID%%
* spJobID: %%JOB_ID_CODE%%

In order to manually construct a personalized link to a landing page a placeholder for spReportId is required. I would like such a placeholder to exist.
