Would it be possible to expose an environment variable that contained the change descriptions of all the changes in this current build.

I have a Publish Assets Post-build action that I'd like to reference the change descriptions of all the changes it's building.

Currently I have the following text:

 Jenkins: ${JOB_NAME} automated build submission.

I'd like to do something like the following:

Jenkins: ${JOB_NAME} automated build submission.

Changes included:
    ${P4_CHANGE_DESCRIPTIONS}
