Show Health Bars of players to only one of them?

Hi, I'm mastering a 5e campaign and I was wondering if I could show the health bars of the players to the healer of the group ONLY! Can I? Thanks :)

Short answer: Only if you allow the healer character to be able to control and edit all of those PCs. They would also share vision with them, though. You could adapt this idea from the  Stupid Tricks  thread, and make the report tokens only controllable by the PC but it would require some jiggery-pokery with the settings and some non-trivial prepwork: Using Tokens to Show Dynamic Data   - Martijn S
