Localization :: Add New Resource File Dynamically At Run-time?

In our web application we need to keep various company's settings. For eg "Shippingpickup","ZipCodeCaption","DefaultCountry","AllowToEditInvoice", etc

These settings are different for various companies and are placed in web.config as key-value pair.

Initially, we have tried do simplify this process by adding a company_settings table in the DB so as to allow us to add companies on the fly. However, this method makes it very difficult to add a new setting since it would require us to add a column to the company_settings table and thus would require code changes as well as stored procedure changes.

Now we have added separate global resource files for each company's settings. But, whenever we want to add new company to our website, we need to add a new resource file for that company. Adding a resource file requires compilation, and thus the application needs to be restarted. I was wondering if there is a way that we can add a new resource file dynamically at run-time.

Or are resource files not the right thing to use here? Is there a better method of tackling this issue?
