Morph box list

Hello Everyone,

Quick Quesiton

I have an adjustable number of arrayed planar surfaces from which I generate  morph boxes...

I've successfully placed objects within theses boxes...

My question is:

Lets say I have a large list of different objects(like a bunch of different houses) how would I place them into the morph boxes one after the other so that I get a whole row of different objects, morphed into the different boxes?

My problem right now is that If I select more than one object they simply all get morphed into each box.
