Basic Max help with vray proxy and multi/sub object maps

Hi All

I just wondered if there was a quick way of doing this:

When you create a vray proxy you need to create 1 multi/sub object maps for each proxy object.

Is there a way to quickly condense a range of matts into one?

Normally I would do this when attaching the meshes, but I dont want to attach all the meshes so can I do this another way?

Hope that makes sense, I sure there is an easy way around this & its just me being dumb!

Thanks for your help.
