Features requests from OnApp customers

When creating a virtual machine, a default template is selected (ex:CENT OS) If you click on another template (ex: Microsoft 2016) and do not select a version, the default template (CENT OS) version shows as unselected, and allows you to continue to create a virtual machine, as the next button is enabled.

There is currently no option to not have a default template and disable the next button to allow the user to not proceed, and select a OS version that they actually want, without having to go back wondering what happened. This causes confusion and a bad user experience.
