Configurations in drawings

I have a part which has four configurations, two of which have threads in a particular region and two of which are just bored for freeze plugs.  Is there a way to to have notes which show up in one configuration and not in another, or alternatively to show up differently?

For instance, in one configuration the note would indicate a threaded hole, the other a reamed hole.

Thanks in advance
