Thanks for this suggestion. Its been made by several customers in the past, and we are looking into ways of addressing this problem in future releases of HealthFrame.
I'm not sure how directly we will support this in HealthFrame v3, but probably by HealthFrame v3.1 we will have an improved answer.
However, please be aware, in the current version of HealthFrame - there is a reasonable answer - copy and paste. You can copy and paste family members from one PHR to another.
This doesn't provide automatic synchronization o information across PHRs (what you and many others have requested) - but it makes it not terribly time consuming to manually copy changes from one PHR to each of a handful of others.
I'm sorry we don't have a better answers right now, but thank you kindly for your feedback!
Support Team.
