Hello! Thank you for reaching out to us!
Unfortunately, currently there is no support for creating a custom compliance group.
In order to do so you would need to write your own script mapping the data in a way that Wazuh can understand, this would affect the whole ruleset and would be overwritten in the process of a version upgrade.
These changes would also not be supported by the API or the Wazuh Dashboard app.
I would recommend you open an issue with our team in the wazuh repository to ask for this feature
