[Xymon] batch configuration of critical systems?

Is there a recommended/supported mechanism to configure (and as needed, update or replace the configuration) of critical systems from the command line?

Assume an external database of service levels or priorities, from which the importance of monitored systems can be determined; and probably some heuristics to expand that into which tests for which hosts to treat as critical. I want to write a script to fetch that and create/update/replace the critical systems configuration on a xymon server; not live from the database, but periodically (probably run by cron as needed, e.g. 4x daily weekdays or something like that).
