Hi Tim,
Updating a field definition (adding new options to the select field) is not possible in a script. This would have to be done in a function by interacting with the rest API. The endpoint for updating fields is:
PUT /orgs/{org_id}/types/{type}/fields/{field}
I didn't notice any existing functions that perform this operation, but maybe it's included in one of the utilities functions i'm not aware of. You can see all of the functions here IBM Security App Exchange
