Rerun last task with terminator (rather than a specific task name)

[blooop]

I use a variety of tasks which i select with:

    {
        "key": "f6",
        "command": "workbench.action.tasks.runTask"
    },
    {
        "key": "f5",
        "command": "workbench.action.tasks.restartTask"
    },

However if I have to click the restart task button all the time so wanted to use terminator. I have tried several regexs e.g ".*" but I can't work out how to make terminator restart whatever the last task that was selected with .runTask.

Is this possible?

Thanks
Austin
