Hi there, I don't think you need text mode for this. If you use the 'assignment users' name task report filter, instead of 'assigned to,' that pulls in all those assigned to a task, regardless if they are the primary assignee or not. Then you'd use $$USER.ID.
So assignment users > name = $$USER.ID as part of your filters should give you what you need : )
Then in your report groupings, you'd group by status.
If this helped you, please mark correct to help others : )
