With the new simplified execution order of the command engine I have successfully implemented nested command blocks

So now you can do something like this if you wanted to without needing to call an external script

/selectall -d
{
    /echo [BLOCK 1] %p%f
    /cd %p%f
    /selectall -d
    {
        /echo [BLOCK 2] %p%f
        /cd %p%f
        /selectall -d
        {
            /echo [BLOCK 3] %p%f
            /cd %p%f
        }
    }
}
/uncd
