vstudio.toolset per project configuration

Hey Branimir!

It would be great if vstudio.toolset could be configured per project configuration. For example, let's assume we have two configs: Game|Win32 and Game|x64. The latter uses default toolset (i.e. v140 in vs2015). But I want the first one to support Windows XP, so I need to set the toolset to v140_xp. Seems like there's no way to do it, the toolset is set once and for all, it's the same for all configs. Or am I missing something?
