Sorta - if I understand what you are trying to do, I think this approach would work...
Create a batch file called SolidWorks.bat with the following lines:
\\network_server\custom.bat
[SW Install]\SldWorks.exe
Then, when you run the SolidWorks.bat file, it will run your batch file, then launch SW.
The other approach would be to use a startup macro and the shell command. The only problem with that is that the command inside the shell statement won't get run until after SW is running. Depending on what you are trying to do, that may be either good or bad.
