There is an open ticket which deals with this: https://issues.apache.org/jira/browse/SOLR-12209
I've been very focused though on anything that enhances the Solr Math Expressions or has been needed for the Fusion SQL engine, which is what I work on at LucidWorks. SOLR-12209 doesn't fall into that category. Eventually though I will clear that ticket if someone else doesn't resolve it first.
