I have one script set_path.bat that adds a few custom paths to PATH variable.
What I want is:
That script should get executed every time I open the integrated terminal inside VSCode
OR
How can a few custom paths be appended to PATH variable every time I open up the integrated terminal?
I had a look at terminal.integrated.shell.windows option and tried something like 
"terminal.integrated.shell.windows": "C:\\Windows\\system32\\cmd.exe set_path.bat",
But did not work.
I also had a look at "terminal.integrated.env.windows" and tried to set something like this
"terminal.integrated.env.windows": {
    "PATH": "SOME_PATHS; %PATH%" 
}
But it had a problem resolving %PATH% (as expected) and because of that, the PATH variable just had the customized path. ( I need the default paths in the PATH as well! )
