@Jenny.vdH - I am not aware of any templates, but if I were to use Miro for such tracking, I would just add a Kanban board to a Miro board and add the columns to track the various states, e.g., Sponsored, Committee Review, Voting - I am not familiar with the process, so I used this site for some guidance: https://keating.house.gov/policy-work/legislative-process

You would use Cards in the Kanban to track the bill details – name, key dates, etc.
