As of 2017-08-17 this still seems impossible.

I added a feature request here:

Update 2018:

The issue is now closed as fixed and is available in the standard MS VS installation [source]. A blog post from the MS team goes through the new features [here].

The solution from MS is flexible. You can not only differentiate using paths like you do with --isystem, but for example also by whether you use #include "" or #include <>. The blog post is worth a read to see all the various customization points.
