Reusable groups of row level security policies

Wouldn't it be nice if we could define named groups of row level security policies, and then apply them to new tables with one click instead of creating from scratch for every table? I wouldn't be too sure if Postgres supports anything of this kind, but even if it didn't, it would still be possible to introduce this as a functionality in the Supabase dashboard, and then apply to Postgres one by one behind the scenes.
