Softimage :: How To Cloth Simulate Window Blind

I am trying to cloth simulate a window blind. My problem is as follows : The model is made up of several pieces.

1. the curtain / blind
2. a hard button near the bottom
3. a cord attached to the button
4. a wooden know at the bottom of the cord
5 then finally tassled material

So i want the blind to move like cloth blowing in the wind ( fine no problem i can do that ! ) but the hard button must be hard surface and follow the mesh position of the blind - PROBLEM

Then the cord attached to the button must be cloth dynamic to flap about and then the knob on the bottom hard surface attached to this cord and then the tassels must be cloth.

The only way i can think of to do this without merging the seperate geometry is to simulate the curtain then cash this, the attach the button to a cluster on the curtain, then do the sim on the cord, then cluster attach the knob the cloth the tassels.
