No Mac or Linux Project template?

I’m trying to add Linux support to a MonoGame Windows App project (using MonoGame 3.5) but I cannot find a Linux project template (or one for the Mac, for that matter). The only thing remotely close is a DesktopGL project, which, I’ve read, creates OpenGL projects for Mac, Linux and Windows. Since I already have a Windows project, creating a DesktopGL project only to throw away the Windows version seems a little backwards. Is there a better way to achieve what I want?

The fact that DesktopGL works on all three platforms doesn’t mean you have to throw away your Windows project. Just use the DesktopGL for your Mac or Linux ones.
