Volume select only on already selected polygons?

I am not sure if this is even possible. But here is what I want to do.

I have an object, and I want animate a hole in it. This is a rather simple process of course. I created an animated b/w map in After Effects, loaded the image sequence in the material editor in 3DSMax, but it in an opacity slot of some material and applied it to my object. And because I only wanted this animated opacity on a specific area of the object, I selected those polygons, gave them another material ID, applied a multisup object map to the object and used an UVW map modifier to place the animated texture correctly.

So no problems there.

But, I like to know if this is also possible using a volume select modifier.
If I apply a volume select modifier to my object, and set it to use a texture for the selection with a delete modifier on top of that, it applies it to the whole object, not to the polygons I have selected.

I guess this is normal behavior, and I am not sure of what I am trying to do is possible. But the reason I ask is that with the second method (using a vol. select) I can put a shell modifier on top to give the object some thickness. A texture with an opacity map doesn't give me that.

So any thought on this one would be welcome. Tx.
