Upload without file choser

I am using Upload add-on and I want to set file path without using its default file chooser. Is there any way yo perform this action?

Do I understand correctly that you would like to select the file to be uploaded without user selecting it? That is (I believe) prevented by the operating systems and browsers. Otherwise any website could steal any file from users' machines.

I know it is prevented by browser, however I need to select files and store their path in a list because I add or remove files before uploading them. Then when I press a button upload them one by one. I am not talking about multiupload it does not fit öy needs.
