[Factory Configuration] variable within the shared configuration (factoryconfiguration)

How can we set an attribute on the web.config related with application version or espace version? 

The goal is having something like this in the web.config

 <configuration>
   <appSettings>
     <add key="AppName" value="Oustsystems Application" />
     <add key="AppVersion" value="1.2.3" />
   </appSettings>
   <system.web>

where the AppName and AppVersion are filled dynamically by the espace or application variables

Please go to e-pace tab and add go to Shared Configurations to associate Shared Configurations with any required module or application
