Add option to Lattice2 to update LPE only on release knot.

This could be useful if item is too complex, making previous knots unusable
This can be used in other LPE if anyone want or ping me to it. Maybe could be usefull add similar thing to path parameter,
Same slow item become tooooo slow with bend path.
