Link a new Marker to a new object

Hi guys,

I’m trying the demo version of this wonderful tool and i’m wondering if with this version allows me to create a new marker with a new object related. If yes how? 'cause i’m stucked so hard.
The new marker is ready, the object too. I just need to know how to say: “hey camera, that marker X refers to object Y.”

Thanks in advance,

Tarek
