Appending/extending variables

Hi,

I would like to manage cron via a template in /etc/cron.d/ansible_crontab for example

I would like to have a default variable in the role

crontab:

That will get appended in
group_vars/all
group_vars/group1



.

host_vars/host1



.

At the end i will just have to manage one list of dictionaries in my template. Is this possible?

Thanks,
ilin
