Streamline the usage of parallel scene play

[bmmtstb]

Is your feature request related to a problem? Please describe.
Some functions can be used with scene.play() others can not, it would be helpful for the user to know what to expect. Users may want to execute multiple actions parallel and not one after the other.

Describe the solution you'd like
Somehow return the animatable object so .play() can be used afterwards. So scene.play() can be called for multiple objects at once.

Additional context
e.g. move_vertex_to() can not be called for two vertices at the same time.
