Is it possible to turn off the default javascript multi-line behaviour?

I'm using a lot of multi-line strings in javascript, for templating purposes.

For instance

var foo = "\
    <div id="{{id}}" {{attrs}} >\
       <ul>\
            <li><a href="#"><strong>Toronto</strong>2004</a></li>\
       </ul>\
    </div>",

The \ character is used to make the multi-line string valid JavaScript.  What's rather annoying is that each time I try to insert a new line PhpStorm automatically inserts a closing " and a + and a " on the next line, thus breaking my carefully-laid out code.   It's assuming that I want to do multi line strings by concatenating strings for each line.

Is it possible to disable this? I couldn't find an option anywhere.
Thanks!
