No, see AI Studio now supports at-mentioning teams! the team members and team admins is what you get in the context window.
Nope, that’s the only way, and even this is limited. We ran a few tests, and are discussing with Asana, it looks like you can’t mention more than 100 elements otherwise the rule can’t be saved.
What you are trying to do is currently not something AI Studio is equipped to handle I am afraid.
