Currently, with the siblings pupils having same dad but different moms or against, we cannot link them as siblings and we have to choose to link pupils onto the same dad/same mom contacts instead and those same dad/same mom contacts becomes the private contacts. this is not the proper way to do this. the private contacts mean 'cannot share' so some other 3rd party system such as CHQ ignore those contacts to their interface. And we found the checking of siblings and family discount are difficult too.
So we suggest to implement the way to link pupils who have same dad but different moms or against as siblings.
thank you,
