At the moment, it's not possible to link certain team members to specific services. This is something we would like to enable in future and we will keep this page updated!
In the meantime, we recommend creating a different page for each of your services. Then you can add the appropriate team member for each one (or you can create a separate page for each team member and then list the services that they do - it just depends if your clients choose services first or team member first).
You can read more about how page work on this page: Setting up separate booking pages.
