Force constraint to reset the transforms?! [HELP]

[johnsonalpha]

basically i have 6 rigid bodies constrained together i have the iterations set to 0 so they move and give a bit during the simulation the problem is that i don't want the constraints to go back to the initial constraint position i want them update the initial transform position. Basically the constraint initial position will be the current position so it doesn't try and perserve the initial position.

How would i do that?!
