I'm not very optimistic about this. At their current rate, Meshmellow (the new owners of Muvizu) don't seem to be at the stage to add even minor features. Adding your suggested feature would be a massive task and I'm not sure the payoff would be big enough to justify all the man hours.
The Unreal 3 engine on which Muvizu is based is almost obsolete at this point (In 5 or so years, Muvizu will really start showing its age), so I think we will have to just work with what we've got. Maybe soon there will be a similar enough alternative to Muvizu from Meshmellow or another company.
