Sub- assemblies in Assembly

Whwn I insert a sub-assembly through Insert Components command, and then fix the position of the sub assembly with respect to the main assembly, then all the components associated with the sub assembly gets fixed. Whereas in the sub assembly there are some movable parts i.e., rotating parts with limit mates.

Can anyone guide me out for how to get the mating conditions of the sub-assembly in rthe main assembly as well.
