Change .suo file

I need to modify the .suo file.

Basically, I have a client-server application. The client requires a "cookie" to log into the server, which is created every day and retrieved on the client machine by another process. This cookie must be set in the Command Debug Arguments.

I want to automate this process by modifying the .suo file directly through another application / script. Is there a way I can do this?

I looked at a tool to view the contents of a solution options file (.suo) but it didn't help. I have no idea about these methods and need a little more direction.
