Subsidiary usage with Invoice Processing for US

Can someone please explain a use case or need to use the Subsidiary option inside the IP Solution?

I have a customer that manages multiple GL accounts for many different internal companies (not Vendors), would I want multiple Subsidiary options, or just use additional columns in the GL options dialogs...

Thanks in advance!
