first image target then groundplane

Hi everyone.

My problem is this:  i have two (or more) different image targets with different models on them. I want to be able to scan a marker, then place the object using the ground plane. 

so far i did not have any luck doing this. 

is this possible?  I found another thread here with a couple of suggestions but nothing seems to work like i want it to.

The image target is just there so the user knows if its model one or two they are going to place
