How can we execute only new task in Ansible playbook? - ansible

Question

We have bit huge ansible tasks in main.yaml and we don't need to execute all tasks, only new task 'House Keep Task' is enough. So tried '--start-at-task' option as below, but Ansible can't find that task;
command :
ansible-playbook -u sysadmin -i ./inventories/dev/hosts --start-at-task='House Keep Task' --step batchservers.yml -K
message :
[ERROR]: No matching task "House Keep Task" found. Note: --start-at-task can only follow static includes.
batchserver.yaml
---
- hosts: batchservers
become: true
tasks:
- import_role:
name: batchservers
tags: [batch]
ansible/roles/batchservers/tasks/main.yaml
---
- name: Add SHARED_DATA_PATH env
lineinfile:
dest: ~/.bash_profile
line: export SHARED_DATA_PATH=/data
- name: Create /data if it does not exist
file:
path: /data
state: directory
mode: og+w
... other tasks include reboot task ...
- name: House Keep Task
cron:
name: "House Keep Task"
user: "{{ batch_user }}"
special_time: daily
job: "/usr/bin/find /var/log -name '*.log' -mtime +6 -type f -delete"
state: present
Is there any good way to execute particular task, House Keep Task?
Our ansible version is core 2.11.12.
Any advice would be highly apprciated.

Q: "Execute particular task House Keep Task."
A: The ansible-playbook option --start-at-task works as expected
--start-at-task 'START_AT_TASK'
start the playbook at the task matching this name
