Run multiple instances of the same task in VS Code

Question

I have created a task in VS Code in order to run my python scripts "on the push of a button", but now I want to experiment with sockets, so I want to run a server and a client at the same time. Server starts without any problem, but when I try to fire up the client, VS Code tells me that "The task 'Python (servcmd)' is already active.". Here is the task I created:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Python",
            "type": "shell",
            "command": "python",
            "args": [
                "${file}"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

So how do I run multiple instances of the same task at once? Or if this isn't possible, how can I run multiple python scripts at the same time in VS Code without having to write any command line? Thanks!
