Physics Animation Help


I have a wall of 845 same size brick objects as in the picture, that I need to collapse. I am planning to create a large invisible box as the size of the wall and rotate the large box to push the 845 bricks.

It takes ages with MassFx to just set these as rigid bodies, so I’m worried about starting the simulation as there will be inevitable further tweaking to achieve an acceptable result. What is the more efficient approach here?

Edit: While waiting for an answer, I tried baking the scene without adding the pushing surface and the wall actually collapsed without much problems but towards its base just as the sim has started. I need time to push the brick wall so they need to stay for some time. The bricks are just one over the other (No slightest space between any two adjacent bricks)
