Is it possible to update the host prototype to create macro entries for the UUID rather then setting the hostname as the UUID. This will allow you to have both monitoring from the VMWare and the zabbix_agentd side of things rather then having 2 hosts for all Virtual Guests.

So right now we have a zabbix installation monitoring for VCenter, but we have 2 entires 1 for the VMWare Guest items (Cluster/host/etc..) and 1 for the actual zabbix_agentd items.
