asp.net - How can I reference an appSetting in a different part of web.config

Question

I have my appSettings defined in a separate config file called Appsettings.Dev.Config, and I include that file inside my web.config file like so

<appSettings configSource="ConfigFilesAppSettings.Dev.config"/>

Lets say one of the settings in the file is

<add key="MailerEmailAccount" value="myemail@myserver.com" />

Can I access the value of the setting MailerEmailAccount elsewhere inside web.config? How?

Nope, the web configuration file cannot pull "settings" from itself; it's not dynamic at all. The only sort of dynamic functionality is the ability to include other .config, but that's just a "suck all these settings in as if they were part of me" kind of thing.
