Activity automation in Emails and Activities

The Email and Activities app seems to focus on the email part of things. I am using it to log calls and meetings, etc, and would find it helpful to create an automation where when I log a TYPE of activity, I can do NEXT STEP (take to next stage, set up a calendar reminder, notify team member, etc).

Is there a way to do this? So far, the only automations supported by this are email integrations. Am I missing something?
