In the formative Markbook you do have the option to enter summative data at the bottom, however this will not be pulled from any formative data entered, as the summative data is based on Teacher judgement.
Within a school you could work out a mapping, that if a student was at a certain percentage secure in the formative area, that would make them on track in the summative area - but this would still need to be entered manually to the summative Markbook.
