You may upload relevant documents as in relevant to your daughters application to any given categories. Simply carry originals and photocopies for your appointment.

I did this and it went fine. Above link I shared everything, you don't need to upload everything mentioned there, similarly everything you need to upload isn't mentioned there. As long as you keep your document size limit below 1000kb you may even bundle couple of documents together.

Thank you very Much dontringthebell
