While you can continue to edit your information after you have submitted your document up until the submission deadline, we recommend you submit once you are happy that your submission is ready to be viewed by our research team.  
The information you upload to the submission hub can be saved as you go, downloaded, reviewed, and edited continually before you submit to enable you to submit with comfort and confidence.
