My discovery returns a macro containing the group the host should be added to. I have tried to add this as "Group Prototype" but this results in the first discoverer creating the group and all subsequent discoveries (there are ~14 currently in the same template) are failing because the group already exists.

It would be nice if a discovered host would:

• If the host group does not exist, create it and assign it to the host
• If the host group does not already exist, do not create the host group it but simply use it in the discovered host
