Linking Vrscene-Object to camera & grouping a Vrscene

Hello,
this is just a knowledge question:

I have an object (character) loaded as a Vrscene into 3dsmax.
The character should be constraint to the camera.
I was able to make a link constraint with Keyframes, so that the object is always moving and rotating with the camera (at least when “set key” is activated).

- But this is only possible when I work with key frames.
Is there any other way to handle a task like this in 3dsMax?

- I also realized, that I can’t use a vrayscene in a group (although I can use it in Maya with a group, to move it)
Is that correct or did I miss something?

Thanks!

(sorry if this is a noob question)
