No option to select build targets

I'm new to Xamarin and am not being prompted for my build targets. I have VS2015 community installed. When I start a new cross-platform project I get six relevant options 1,2) Blank App (Protable/Shared), 3,4) Blank App (Xamarin,.Forms Portable/Shared, 5,6) Blank Xamp App (Xamarin.Forms Portable Shared).

I keep seeing tutorials where they say "Create new project, and when prompted for your target platforms select ...", but I don't get that option.
1,2 always generate Droid, iOS, WinPhone
3,4,5,6 always generate Droid, iOS, UWP, Windows, WinPhone

Question 1) How can I select my targets when I create a new project?
Question 2) Can I add new targets later on? I'd like to start with a Droid/Windows project, then later add the UWP and WindowsPhone, then even later add the iOS. Is that feasible or not recommended.

Thank you!
