Multiple removing e-mail attachments

[_Mono_]

Hi!

I'm new here and sorry for by bad English.
We want to buy a Zimbra 7 Network Edition. Our management want remove the attachments from the user's mailboxes periodically.
The e-mails should be remain.
I know the quota is a good solution but my management.... :S

So I found on the admin panel a very good search function. I can set a date range with attachment type, attachment size, etc. filter but the search result is show only a specified mailbox.
Unfortunately I can't see a "remove attachments from this results" function

Can do this the Zimbra?
Dou you have any idea how can I do this "request"?

Thanks,
Peter
