Exchange Address List - show both users and groups

We have a hosted environment where multiple customers run on the same Exchange 2003 server.
Each customer is assigned a customer number (fx. 1234) and a country-code (fx. dk), which combined is used as a suffix in the userPrincipalName (username@1234.dk). Similarily the names of groups are also appended with the suffix (groupname@1234.dk).

Each customer has it's own Global Address List that displays Exchange users with userPrincipalName=*1234.dk, so their Exchange Address list only displays the users from the particular customer (each GAL is assigned special permissions).

We can also create a seperate Address List for each customer, that shows the groups which has 1234.dk in the name (cn=*1234.dk).

But we would like to be able to construct an address list that shows BOTH users with userPrincipalName=*1234.dk AND groups with cn=*1234.dk on the SAME address list.

Is this possible?

This custom query will show all Exchange users from business 1234.dk:
(&(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(objectCategory=group) )))(objectCategory=user)(userPrincipalName=*1234.dk)))

This (custom query will show all Exchange groups from business 1234.dk:
(&(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(objectCategory=group) )))(objectCategory=group)(cn=*1234.dk)))

But how can these be combined?

These shortened LDAP queries also work:
(userPrincipalName=*1234.dk)
...and...
(cn=*1234.dk)

But can they be combined?

This DOESN'T work:

(userPrincipalName=*1234.dk)|(cn=*1234.dk)
(userPrincipalName=*1234.dk)(cn=*1234.dk)
(userPrincipalName=*1234.dk)&(cn=*1234.dk)

Any help on combining user and group LDAP queries will be hughly appreciated!!!
