Of course, this assumes I haven't missed something...
In Solidworks, you can right click on a sub assembly, go to Properties, then in the Properties window set the assembly from Rigid to Flexible. Sub assemblies are Rigid by default, but selecting Flexible allows them to move however the mates in the sub assembly were set up.
