EDMCS - Passing Node Type Properties Across Applications

Content

I have created a custom application, "Reference Data" where I've created a custom property "Legal Entity" and assigned it as a Node Type.  I'd like to be able to use this same property in my Planning and EBS applications, but it errors out stating I have to define it in my app registration.  I cannot add any custom properties with the "Node" type to my predefined Planning/EBS apps.  Is there a work around for attaching a hierarchy to a property within a predefined application type.  I would prefer not to create an entirely custom app for this property.
