At the moment it is possible to indicate if elements of a register are mandatory or optional, but it would be useful to be able to specify 'Mandatory only if On Register'.
For example, the SEND Status star ... it should not be possible to add a pupil to the Register without allocating them a SEND Status value, hence the field should be Mandatory. However, if a pupil is later removed from the register by marking as 'Off Register' then their previously allocated 'star' continues to display in Student Manager etc, but it is not possible to delete the star from their record while that register field is marked as Mandatory.
