When I copy a job with promotions the promotions are not copied with the job, the promotions directory on the filesystem is empty on the created job, my current solution is to modify these via powershell manually.

Promoted builds creates a file structure like this:
promotions/
...................Promotion.1/
.......................................config.xml
.......................................builds/
...................Promotion.2/
.......................................config.xml
.......................................builds/
