Limit a collection

Good,
I'd like to know if there is a Query in SCCM 2007 that would prevent adding a pc in a collection that is excluded to another collection

For now I have this Query to exclude the collection:

<select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.ResourceId not in (select ResourceID from SMS_CM_RES_COLL_xxxx)>
