Preview Transform and Add Transform OOB Issue with other config type

Configuration Transformation: Evironment Configuration

XDT: Transform

In recent times I have been working sitecore configuration config transformation for different environment and I came across the scenario where Add transform and Preview is supported in Visual studio only for web.config files not for other configuration. To fix this I just install Slow Cheetah extension and restarted my visual studio with project solution , everything works fine.
