Pack the whole solution into a single nupkg?

I have a number of helper libraries that I would like to turn into a single NuGet package:

ProjectAProjectB (references ProjectA)ProjectC

I can make individual packages of these:

nuget pack ProjectA.nuspecnuget pack ProjectB.nuspecnuget pack ProjectC.nuspec

Or I can "bundles" of referencing projects:

nuget pack ProjectB.nuspec -IncludeReferencedProjectsnuget pack ProjectC.nuspec

But I'd very much like a single .nupkg file containing all the projects.

Is this possiblie to achieve?
