You can not run two campaigns for the same track at the same time. If you would like to have another campaign for the same track, please wait until your campaign ends and relaunch it using the c feature. This way the song will be sent to a different group of curators, the curators who reviewed your track initially, won't receive it again.
Once your campaign finishes, you might also set up a brand-new campaign for your song from scratch. However, we do not recommend doing it as the song might be received by the same curators for the review.
