##### SUMMARY
[`zabbix_host`](https://docs.ansible.com/ansible/latest/modules/zabbix_host_module.html) module currently does not support specifying usermacros.

While usermacros can be added separately with [`zabbix_hostmacro`](https://docs.ansible.com/ansible/latest/modules/zabbix_hostmacro_module.html) module, that splits up the configuration and makes it very hard to maintain.

It would be great to specify macros in the host definition of `zabbix_host`.
