Single clip with multiple members?

Hi everyone!
Would it be possible to generate an animation clip for a number of objects (not an armature)? I used this feature in Maya a lot and can not find a replacement for this.

As an example, i want to animate several objects (like an explosion or a weapon consisting of multiple parts) and place all members in a single clip. This clip could then easily be streched or repositioned or exported as a single entity. Is it correct that I would have to create a single clip for every object?

Thanks and all the best
