Organizing Matters for Law Practice

Hi All. We’re organizing monday for a law practice and client matters, each with a set of tasks. We’d like to have one place where each matter has a list of tasks and another place where we can see a top-level view of the status.

Idea 1: Each matter is it’s own board with plenty of room to organize tasks/items. But, that’s a lot of boards.

Idea 2: Each matter is an item in a master board with lots of subtasks. But, I don’t love subtasks, they don’t appear in My Work clearly, and they don’t seem to be usable in mirror columns.

Idea 3: Each matter is a group on a single board. But, problems with mirroring again–can you pull in a group name?

Any thoughts?
