Overriding build goal while performing a release

The current release plugin performs a build twice when a release is done. It does one build using the default build goal and then it builds again using the release goal. I am trying to override the default build goal and just perform the release goal at time of release. To do so we need to have the release goal input from the user so have added one more field in the configuration environment. Kindly see the attached image.

Thought this option is available in pre release menu but still it does not override the default build and performs two builds at time of release which take more time.
