Sharing configuration settings between Windows Azure roles

My Azure project has a Web role and a working role. Both roles have some common configurations.

How could I share configurations instead of repeating for both roles.

Now the cscfg file looks like this

<ServiceConfiguration serviceName="xxx" ....>
  <Role name="WebRole1">
     <Instances count="1" />
     <ConfigurationSettings>
        ....
        <Setting name="setting1" value="" />
        <Setting name="setting2" value="" />
      </ConfigurationSettings> 
     <Certificates>
     .....
     </Certificates>
  </Role>
  <Role name="WorkerRole1">
     <Instances count="1" />
     <ConfigurationSettings>
         ....
         <Setting name="setting1" value="" />
         <Setting name="setting2" value="" />
     </ConfigurationSettings> 
     <Certificates>
     .....
     </Certificates>
  </Role>
</ServiceConfiguration>

After googling, I found this http://www.simple-talk.com/blogs/2011/03/16/sharing-configuration-settings-between-windows-azure-roles/ - is there an easy way to achieve the same?
