Angular2 patchValue push value into array

Question

Is it It looks like Angular2\'s FormGroup.patchValue() doesn\'t push new elements into an array.

For example something like this:

ngOnInit() {

Well, as silentsod said, it is not possible. Currently, I am using below as an alternative:

        let controlArray = this.form.controls['apps'];           
        this.list.forEach(app => {
                    const fb = this.buildGroup();
                    fb.patchValue(app);
                    controlArray.push(fb);
            });

Angular Team - We need a new function something like PatchArray() that would patch from a collection/object graph. It is a basic use case.
