Organize Shared Inboxes in a Workspace

It would be great to have the possibility to add folders or some separator that you can name for teams.

Currently it's like:

Shared

- WORKSPACE NAME

-- SHARED INBOX 1

-- SHARED INBOX 2

I would like the possibility to have it like:

Shared

- WORKSPACE NAME

-- For example, "Accounting" (that behaves like the "View" feature)

--- SHARED INBOX 1 (that includes for example accounting@domain.com)

--- SHARED INBOX 2 (that includes for example invoices@domain.com)

I know that you can create views, but sometimes it's easier to work on one inbox after the other than in a view that mixes every conversation from different inboxes.
