The limitations when filtering Conversations makes it incredibly hard to use it efficiently as a team.

Currently there is only an option to filter by "Last activity" but there should be an option to filter by "Last contact activity" (type & channel) from the contact.

For example, I don't see the option to filter these conversations by "Last Contact Activity Channel - Phone" because when we send an email blast to our entire contact list or they're in an email automation, the most recent activity will show email and I don't actually get to filter by the contacts last activity. You need to be able to filter in conversations by "Last Activity from Contact is: x".
