CC2017 outputModule.file auto overwrite option

I have a script that with one click it automatically sets my comp to render queue and starts to render immediately + remove the item from RQ/close the RQ window after the process...all that is working very fine and I am happy with it.

my problem is quite annoying: I want my script automatically overwrite the output file if it exist without asking me - is there some kind of "switch"in the code to tell the script "yes, overwrite that existing file?"

Here is my code:

var item = app.project.activeItem;

if (item != null)

{

var rq = app.project.renderQueue;

var render = rq.items.add(item);

var settings = {

"Quality":"Draft",

"Resolution":"Half",

"Time Span":"Work Area Only",

"Color Depth":"32 bits per channel"

};

render.setSettings(settings);

render.outputModules[1].applyTemplate("Lossless");

var crop_data = {

"Crop":true,

"Crop Bottom":100,

"Crop Left":100,

"Crop Right":100,

"Crop Top":100

};

render.outputModules[1].setSettings(crop_data);

var folder = app.project.file.parent.fsName;

render.outputModules[1].file = new File(folder + "/" + item.name + " [DRAFT].avi");

rq.render();

render.remove();

rq.showWindow(false);

}

else

{

alert("You have to click inside some active composition timeline first!");

}
