Deletition of backups

Is there a way to delete selected backups from the ASZ with the media disk?
I can see the options within Acronis when installed of the system.

I like to do partition backs from the media disk and would like to try and avoid having ATI2011 installed.

If its not possible with 2011 does anyone know if 2012 has this option within the media disk.

Thanks,
