Signing to the same family from different devices

Hello-

I created a family in Garmin Jr with my account and added my two children. My son has an iPod and I’d like him to be able to access his account/ data in a child’s mode, without access to his sister’s account/data. I was able to connect the same family on his iPod, but then he can access the full data set, not only his. Is there any way to set-up family/ accounts so that each child can see only his data in a family? 

thanks so much in advance
