In your handler file, chain the different steps together using notify.

- name: Restart conditionally
  debug: msg=Step1
  changed_when: True
  notify: Restart conditionally step 2

- name: Restart conditionally step 2
  debug: msg=Step2
  changed_when: True
  notify: Restart conditionally step 3

- name: Restart conditionally step 3
  debug: msg=Step3

Then refer to it from a task with notify: Restart conditionally.

Note that you can only notify to handlers below the current one. So for example, Restart conditionally step 2 can't notify Restart conditionally.
