Disable constraints in a load step.

Hi. I have a model consisting of several parts held together by bolts. Firctional contact is applied between the bodies. The bolts will be pre tensionsed in 3 stages. Due to this configuration the model is not very stable and I have issues getting it to converge.

What i would like to do is to add a zero displacement to some of the parts i the first 2 load steps, so that the bolt pre tensioning steps will converge. Thereafter I would like to disable the displacement before i apply the external loads. Is this possible?

Your help i appreciated.
