[Dovecot] Editing sieve files

Hi all

I've got a standard dovecot setup: home is /var/spool/vmail/domain/user/ uid: vmail gid: vmail Sieve file is: /var/spool/vmail/domain/user/.dovecot.sieve

if i want to change the dovecot-sieve file to modify the rules (or even let my users do it at some point) then it has to been done by root.

Is there a way to setup the sieve plugin so a user can create his own rules? sort of like ~/.procmailrc

TIA jalal
