[Dovecot] home_location or smth like that

hi dovecot list help me please

dovecot-1.0.r27 exim lda virtual users in ldap base

i decided to start using the sieve pluging so i have to make the homes
(now my homeDirectory in ldapbase is /nonexistent). there is a lot of users, so i dont wonna to make changes in every ldap
record + imho the hard link to userhome in ldap - its a not good idea.

so is there any way to make it easy? may be like home_location = bla-bla-bla/%n/home in dovecot.conf (or in
dovecot-ldap.conf )

sorry for my english
