Create an individual URL for email campaign (same behavior that trackers)

Dear all,

I want to upgrade the campaign feature to be able to generate an individual URL from a campaign email (for instance to access a private webform with my identifier and other pre-filled fields).

For me, it's quite similar to the tracker feature.

My question is easy : where can I do that ? Where Sugar is managing the replacement of the standard tracker by his personal tracker ?

Matt Marum, Francesca Shiekh, Angel Magana, Cédric Mourizard any idea ???

Many thanks for your help,

Fred
