Importing images as a sequence in Adobe Premiere Pro using extendscript

So I've been looking around and trying to find a way of importing image sequences in Adobe Premiere Pro using extendscript.

I can import separate single files using: app.project.importFiles(new Folder(folder_path));

But I can't give an option of importing these images as a sequence.

I tried using opts = new ImportOptions(new File("path_to_image")); opts.sequence = true; and calling this within app.project.importFiles(opts) but Premiere doesn't seem to support ImportOptions, I keep getting an error stating "Import Options does not have a constructor"....

I'm assuming Premiere Pro doesn't support ImportOptions?

Is there any other way of importing an image sequence using app.project.importFiles?

Thanks!
