Using script to assign custom default fields

I have a powershell script that gets me the AD site name of the local host. It also gives me the IP address of the local host given the hostname. I'd like to add the output of this script as default (metadata) fields for all my events. Is this possible?

For example, host, source, sourcetype (among others) are metadata fields given to me by default. I'd like to add the fields "site" and "ip" (that values of which are provided to me by the script) to the list of metadata fields.

Thanks. Through some more investigation, it seems like automatic lookups are a better option for me and not as invasive as custom metadata/default fields. I can populate the lookup table through periodic running of a saved search that would take the latest host-ip-site data and populate a lookup table, then the automatic lookup will add the ip and site fields to the search results.

Also, looks like I can search on the ip and site fields as well (and not just display on search results), which is great and fulfills my requirements.
