grouping composition objects for mix or mutes

[rolandcahen]

It is really important to be able to group all the audiosources of the same composition under a general slider or mute or disable in order to check sounds and lights whitout and with the whole composition and not only with individual AudioSources or Lights whitch is really too long.
Individual AS settings (volume...) are usefull to ajust each audio source of a composition, but when you have many compositions in a space, what you want is usually to activiate or deactivate whole composition.

[rolandcahen]

There should be a heyrarchical classification of SPACE:
SPACE
COMPOSITION
COMPONENT (AudioSource/Light...)
Or at least a mute for each composition
