It is now a requirement that centres submit via the Text and Task tool in the first instance. This is to ensure parity across centres in terms of their access to advice, as well as ensuring this information is logged more carefully. The tool automatically generates a connection between your centre and your submission which means you will not be contacted come the submission deadline (31st January in the year of examination).
It should be noted that submission through the tool is not final, these come through to Isobel in the Subject Advisor team where she can either approve as is or send back some advice for rephrasing. She will let you know in either case whether another submission is necessary.
