Changing scm data when performing scm:tag or scm:branch

[Scott Carter]

Is there a way to update the scm configuration within a pom when scm:tag or
scm:branch are run.  The scm configuration has the defined <connection> and
<developerConnection> that for example point to a correct trunk location.
 When that code branches the path is no longer accurate, so I wanted to know
if there was an easy way to update this.
Thanks
