Hi @Ethan_Parker and welcome to the community!
Since no one else is answering, I’m gonna take a shot. It seems to me, one solution could be to have 3 tables:
- clients (linked to 2.)
- volunteers (linked to 2.)
In that way, you could see in table 2 which clients and volunteers are linked to the symptoms. In a paid version, you could then, for example, install the matrix app to visualize things.
Just my very simple first thought.
