+If you want to add extra field types that do not return one of the known values, you can add it as such:
+
+```yaml
+SilverLeague\IDEAnnotator\DataObjectAnnotator:
+  dbfield_tagnames:
+    Symbiote\MultiValueField\ORM\FieldType\MultiValueField: 'MultiValueField|string[]'

 **NOTE**
 
 - Using short names, will also shorten core names like `ManyManyList`, you'll have to adjust your use statements to work.
