v0.12.4+ is already contains similar logic in BuildComponent.

Now it should be easier, for example:

#[Build solution.path("app.sln").First.name]
#[Build solution.current.Last.path]
...
#[( #[Build solution.current.GuidList] ~= "{4262A1DC-768F-43CC-85F5-A4ED9CD034CC}" )
{
   ...
}]
...

etc.

Available a few variants for different modes.
