yeah, go to the immigration website and apply, put all your documents, it will allow you to see how the process works. you will see, the documents must not exceed a certain size, etc.... and you do not finish the application and then you delete your application. that way you can do as many as you want without validating them, while your file is perfect... and yes at the end it asks you for the flight and accommodation but no need for a reservation, just the dates and the flight number, personally I booked them because I am sure to go on vacation if I do not have the DTV :.. 😅
