Animate CC 2017 code to go to a particular frame in a flat file

I use Animate CC 2017 on a Mac and generate output as html and js files. I use the following code to call one html file from another:

this.downarrow.addEventListener("click", function (event)

{

  window.open("SkeletalLL3.html", "_self");

});

It works just fine. However, is it possible to add some additional code that doesn't start the called html file from frame 0 but rather goes to another labelled frame further down the timeline?

Thanks
