In the Priority Inbox, you can filter engagement displayed by channel/service, however, I would like to be able to filter by Service List as well, so that it displays all engagement for my client, whose services I have placed in one service list, and so that I don't have to select each service one by one every time, for all of my clients.

Some of my clients have multiple Pages and Instagram accounts, and this can be very time consuming to filter each one out individually every time.
