Actually using vmware.hv.discovery only allows to put the discovered hosts in static groups or in group prototypes defined at the template level.

We currently monitor lots of customers, each customer has his own group. What I would like to do is to place each customer hypervisors in the existing customer group.

Currently this is not possible unless you stop using the templates and configure each vCenter with his own static group.

Having lots (hundreds) of vCenters this is not the best way to go...

If only the group was "unlocked" once the template is applied I could set the correct group
