Currently, no, that's not something Kibana does out of the box, and I don't think that the Lucene query language allows you to get the total. I think the reason is that it's not something Elasticsearch does, and we have historically tried not to add features in Kibana that we can't do in Elasticsearch, though I think that mindset is changing.
I'm pretty confident that pipeline aggs would allow you to do this pretty easily, but Kibana currently doesn't provide any way to use them.
It's also possible that the new Painless scripting language in Elasticsearch will allow this, but I'm not really familiar with it myself, so you'd have to flip through the docs yourself to see if that's right.
Also, here's an issue in the Kibana repo to track this: https://github.com/elastic/kibana/issues/4528
