As per a comment I added on the VS Marketplace, and the response I received, I'm adding this suggestion.

We currently have 9 different packages created from a single solution build, and are currently using octopack to do so. This allows me to keep the build definition concise and easily managed. However, if the octopack step fails, it requires work to determine that the solution build itself has not failed, that it was octopack.

I'd love to be able to separate out the package creation from the actual solution build, but ideally I don't want to have to add 9 Packange Application steps to my build if I can avoid it.

So I'd like the Package Application step to be capable of packaging multiple nuget or zip packages at once, the way octopack is able to.
