Exclude sections from document word count

I am enjoying the updated version of manuscripts and looking forward to the native Mac version. I have a feature request (this may be possible but I could not find how to do it). Most of the journals that I am submitting to have a word count that excludes certain sections of the paper such as the abstract, references, author’s bio etc. It would be great if there was some way (such as a checkbox in the inspector similar to how showing/hiding the section header works now) that these sections could be removed from the overall word count of the document.
