[Boost-build] How should I fix the default b2 compiler to be MSVC 14.2?

I have both MSVC 2017 14.1 and 2019 14.2 configured.

https://boostorg.github.io/build/manual/develop/index.html#bbv2.reference.tools.compilers <https://boostorg.github.io/build/manual/develop/index.html> 

says that by default, the most recent registry entry will be called,  but seems to be 14.1 at present.

How should I ensure that when I call b2 that *by default* the VS 2019 14.2 version is used ?

(I’d rather not have to call with toolset=msvc-14.2 each time – I’m bound to forget ☹ )

Of course, I also want to be able to b2 toolset=msvc-14.1,msvc14.2, gcc-8.1.0 ..

Thanks
