Fileattachment of annotation

We can attach file in comments tool. Is there any way we can place paperclip icon with file through script under button?

Following script can just place paperclip icon but how can add file as well?

var annot = this.addAnnot({
page: 0,
type: "FileAttachment",
author: "A. C. Robat",
name: "test",
rect: [400, 400, 550, 500],
contents: "Try it again, this time with order and method!",
attachIcon: "Paperclip" });

Though we can attach file with importDataObject, my intention in on paperclip.
