将配置部分（特别是WCF部分）拆分为多个配置部分？

Question

我在web.config中有这个部分：

  <system.serviceModel>
    <behaviors configSource="Configuration\Active\ServiceModelBehaviors.config" />
    <services configSource="Configuration\Active\ServiceModelServices.config" />
    <bindings configSource="Configuration\Common\ServiceModelBindings.config" />
    <client configSource="Configuration\Active\ServiceModelClient.config" />
  </system.serviceModel>

我想添加另一个具有不同路径的客户端部分以防止配置重复：

  <system.serviceModel>
    <behaviors configSource="Configuration\Active\ServiceModelBehaviors.config" />
    <services configSource="Configuration\Active\ServiceModelServices.config" />
    <bindings configSource="Configuration\Common\ServiceModelBindings.config" />
    <client configSource="Configuration\Active\ServiceModelClient.config" />
    <client configSource="Configuration\Common\ServiceModelClient.config" /> <!-- this -->
  </system.serviceModel>

我知道某个部分只能出现一次。无论如何我可以解决这个问题吗？像部分部分或什么？
