BUG: {{this.member}} data does not output to system Invoice email

{{this.member}} data does not output to the system Invoice email layout.
It works on the system Workflow email but not the Invoice.

Did you get {{this.member}} to work on a page? I need to check is the user is logged in or not. Any idea how to do that?

Nevermind. I was looking for {{request.is_logged}}.
