Guys, don't you think this feature could be useful? Is there something I can do to convince you? :)

> While importing documents through DataImportHandler I need to remove some fields from the final SolrDocument before it's submitted to Solr.
> My usecase: the import query returns an A column which I use to fill in the B field on the Solr instance. My Solr schema contains both the A and B fields, so they are both filled in through dih. I'd like to force the deletion of A from the generated SolrDocument since I need a value only on the B field and want to leave empty the A field. The only way I found is using ScriptTransformer, so I thought it could be useful to add this feature to the TemplateTransformer.
