How to move rolling shutter "door" in Solidworks?

Hello
I'm trying to make a simulation for rolling shutter door. My problem before starting simulation is in assembly :( I'm using 2012 version but if there is a solution in other versions a could install anyone .
When I make a path mate to a group of slats "like in the Photo" several problems occur
First when I try to drag I just can move the group from the last made mate ! not from anyone else.
Second the slats overlap on each other while moving and it is hardly to separate them :(.I tried to make angle mate to prevent that but it became over diffident!
How could I solve these problems to complete my work
I search a lot about this, but I couldn't find a solution yet :(
