Command Line build step to run after all reports are genereated

is there a way to ensure the command line build step to run after all the generating of the reports (nunit, fxcop, dotcove..etc) are finished.?

currently I have a command line build step (as the last step) that copies files from temp folder, to a different location. However, it is triggered before all the reports are generated.

I am trying to find a way to export all the build step generated xml file output to a different location

Thanks
