Hello,

basically I am looking for a way to to something like this

template Host "template-A" {
    groups += [ "Hostgroup-A" ]
}

template Host "template-B" {
    groups += [ "Hostgroup-B" ]
}

object Host "MyHost" {
    import "template-A"
    import "template-B"
}

with the expected result of MyHost being assigned to both hostgroups. Right now this does not work in Director; the last imported template will simply overwrite the values defined in previously imported templates.

It would be nice to be able to specify whether a given property should be "cumulative" (e.g. use operator += for lists or dictionaries) or "explicit" (overwriting any previously assigned values).

Kind regards
