How can i Limit the space for ALL domains

[m0rpheu5]

Hello guys, i would like to know how can i limit the email space for ALL email accout, like in my old server with cPanel, i had a option that i give 2gb of space for emails, and the client can create unlimited emails but not use more then 2gb of space, in the Plesk 9.5.2 i only found a option to limit the space PER count not for ALL accounts, is there this option??

Thanks
