Hi everyone, how do I go about getting an exploded view of an assembly that consists of a multibody part as well other parts?

For the multibody part,I've used 'Move/Copy' to manually move the individual bodies to place and saved that as a configuration but i'm having trouble getting this to appear 'exploded' in my main assembly. Only the other normal parts could be exploded.

Any help would be greatly appreciated.
