No Touch Deployment and Web Services.

My problem is that same webservice deploys on localhosts,
development server, test server and production server and
i want to control from the shortcut on the desktop on
which server to access webservice from, like this:

C:\WINNT\Microsoft.NET\Framework\v1.1.4322\IEExec.exe
http://ozzy/conet/client/bin/co.win.exe?server=ozzy

the parameter server=ozzy tells which server to run
webservice on.

PS:I've tested the option dynamic on web reference
properties but i cant find a way to programatically change
the settings in application.config file.

Thanks in advance!
