Hi Lucase,
You can add a Private Gallery to Extensions and Updates in Visual Studio.
To add a private gallery to Extensions and Updates
1. On the menu bar, choose Tools, Options.
2. In the Environment node, select Extensions and Updates.
3. Choose the Add button.
4. In the Name field, enter a name for the private gallery, for example, My Gallery.
5. In the URL field, enter the URL of the Atom feed or SharePoint site that is hosting the private gallery.
a. If the host is an Atom feed that connects to the private gallery, the URL would resemble this one:
http://www.mywebsite/mygallery/atom.xml. This URL can refer to a file or a network path.
b. If the host is a SharePoint site, the URL would resemble this one: http://mysharepoint/sites/mygallery/forms/AllItems.aspx.
