How can I temporarily change scalaVersion in all sub-projects of my sbt build?

I like to sometimes try out a different version of scala by using sbt's set command like so:

set scalaVersion := "2.11.6"

However this does not work as expected in a build with sub-projects

If I run set scalaVersion := "2.11.6" in the top-level project and then run show scalaVersion, I get the following:

> show scalaVersion
[info] sub1/*:scalaVersion
[info]  2.10.5
[info] sub2/*:scalaVersion
[info]  2.10.5
[info] master/*:scalaVersion
[info]  2.11.6

If I run test now, nothing really changed because the master project does not actually contain any code, so I am still testing Scala 2.10.5.

Is there an sbt command I am unaware of that would allow me to temporarily change the scalaVersion for all sub-projects?

Try set every scalaVersion := "2.11.6".
