I'm not sure if what you’re asking for exists. I don't believe that the "landing page" is stored in CJ. The advertiser determines the Landing page.
Some advertisers have "redirectable" links. With redirectable links you can choose the page you wish to direct traffic to and add it to the link code.
I wish all advertisers had redirectable links but it seem that some only want publishers to send traffic to the home page.
I hope that this answers you question.
