No, because the behavior gets the strings to work with from the
model's copy of the data that's been set.

The simplest way to handle this would be to create a new column,
username, in the campaigns table. Set that as the field to be
sluggified in the $actsAs array. (Make sure you have a "slug" column,
as well.) In your controller:

$this->data['Campaign']['username'] = $data['User']['first_name']. ' '
. $data['User']['last_name'];

(That's a space between them.)

This assumes that the User data is inside $this->data at the time, of
course. If you want to capture the name of the logged-in User who is
actually saving the Campaign:

$this->data['Campaign']['username'] = $this->Auth->user('first_name')
. ' ' . $this->Auth->user('last_name');

If an admin will be creating Campaigns *on behalf* of some User, then
the first form will be necessary and presumably the admin will be
choosing a User from a list.

So now you've got the full User name as well as a slug in the
campaigns table. So you can use ['Campaign']['slug'] for your URLs,
and ['Campaign']['username'] for display on the page.
