i18n and multiple web modules..

Is there a way to tell Idea to stay away from certain property files, e.g.
I have a project with 2 web modules (site and admin), now, within admin I have admin.properties which is used for i18n stuff within admin webmodule.
When working within site module jsp files, all properties that are defined within admin.properties are not marked as missing within site module (which of course uses site.properties file).
So this auto - discovering stuff is nice, but just not so nice in my case, is there a setting/workaround for this...?
