Move unassigned story to an assignment (for InCopy)

Question

I want to add a stroy to a new assignment with javascript.
I found out how to create an assignment, and how to make a icml and icma document
However it comes in unassigned incopy items, and I can't find a way to place it into my new assignment.
To create an assignment I use:
var myAssignment = myDoc.assignments.add(...);
And to create an icml file I use:
myStory.exportFile(ExportFormat.INCOPY_MARKUP, File(myFileIcml));
Both work, but now I need a way to place the icml into myAssignment. How can this be done?
Thanks!

In my opinion this is one of those rare occasions when functionality available in UI is unavailable to script.
But I think it's possible to workaround this isue like so:
var doc = app.activeDocument;
if (app.selection.length == 0 || app.selection[0].constructor.name != "TextFrame") exit();
var textFrame = app.selection[0];
var assignmentFile = new File("~/Desktop/Test.inca");
var incopyFile = new File("~/Desktop/Test.incx");
var assignment = doc.assignments.add("Test", assignmentFile, {name:"Test"});
var unassignedContent = doc.assignments.item("Unassigned InCopy Content");
textFrame.texts[0].exportFile(ExportFormat.INCOPY_DOCUMENT, incopyFile);
unassignedContent.assignedStories[0].move(LocationOptions.AT_END, assignment);
assignment.update();
P.S. I assume that a single text frame is selected
