Use custom attribute for one entity in model

[rfsebwmk]

Hi,
Suppose, I have a cube as a model.
I apply dynamic attributes.
Is there a way I can make only one face of the cube have the material specified in a custom attribute?
I hope there is a simple solution for this.
Thanks for your replies.

The easiest thing that comes to mind is making that one face a separate component nested inside the cube component.

Maybe someone else would have a different idea.

Thanks.
It works.
And it also works if I make the specific face a group (instead of a component).
