Can I modify Ansible 'remote_tmp' on a per task basis?

I am running some tasks with delegate_to. When those tasks run, they use the same remote_tmp directory setup from the ansible.cfg.
However, due to permissions and directory size issues, I need to change the remote_tmp directory for tasks that I am using delegate_to for.

Example:

- name: Create Temp Dir
  delegate_to: localhost
  file:
    path: "{{ my_temp_dir }}"
    state: directory

I am using Ansible 2.3.2.

As of 2.5, yes, changing remote_tmp, which is an ansible_* variable is something possible, by adding it to the vars of the said task.

For example:

- tempfile:
    state: file
    suffix: temp
  vars:
    ansible_remote_tmp: /tmp/temp_file_1_task

Given a playbook with the two tasks:

- tempfile:
    state: file
    suffix: temp
  vars:
    ansible_remote_tmp: /tmp/temp_file_1_task

- tempfile:
    state: file
    suffix: temp
  vars:
    ansible_remote_tmp: /tmp/temp_file_2_task

A reduced version of the extra verbose log would yield:

<127.0.0.1> EXEC /bin/sh -c '/usr/local/bin/python /tmp/temp_file_1_task/ansible-tmp-1642453716.1902952-890-119314712082250/AnsiballZ_tempfile.py && sleep 0'

and

<127.0.0.1> EXEC /bin/sh -c '/usr/local/bin/python /tmp/temp_file_2_task/ansible-tmp-1642453716.6039782-905-172576654053914/AnsiballZ_tempfile.py && sleep 0'
