Change eclipse's built in tomcat context.xml file using WTP?

Is it possible somehow to modify the contents of the context.xml that eclipse uses when you are doing "Run as" -> "On server"... and "Debug as" -> "on server"

We have some settings that are in our production environments context.xml file and we need them to be available to eclipse built in tomcat as well.

I know we could use eclipse to run run on an external server, but thats not as convenient.
