I understand that OctoPacka and Octo.exe can do this - specify the target Space - but how can we accomplish the same using NuGet.exe push? Unfortunately, we are currently restricted to using NuGet.exe.
The Spaces-ID can be found in your URL when browsing the Octopus portal on any but the default space. (Leaving the space blank will push to the default space)
Example URL while on dashboard: http://OctopusServer/app#/Spaces-22
Does this help?
Let me know if you have any further questions here.
