Limit functionality for only nodes

Hi there,
I've found that this great module has a large amount of potential.

However, is there a way to limit its functionality to specific nodes only, while not touching any content type access permissions, (let drupal and other modules take care of this)?

For example, I am using a forum access module, with different forum containers having different permissions, and I don't want to ruin these fine tuned permissions by setting new settings with NodeAccess. All I need nodeaccess for, is to change the permissions of only ONE forum topic.

Should there be a function that says, "Limit NodeAccess access controls to individual nodes"

Thanks for your help
