Mixed regular and copied properties in ARM template - azure-resource-manager

Question

Using property iteration we can multiply properties in ARM resource. But how can I mix these copied properties with others that are typed explicitly?
What I expect might look like this snippet (of course it's incorrect because "probes" property is duplicated).
"probes": [
{
"name": "FirstProbe",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": 123,
"protocol": "Tcp"
}
},
{
"name": "SecondProbe",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": 456,
"protocol": "Tcp"
}
}
],
"copy": [
{
"name": "probes",
"count": "[length(parameters('someParam'))]",
"input": {
"name": "[concat('OtherProbe', parameters('someParam')[copyindex('probes')])]",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": "[parameters('someParam')[copyindex('probes')]]",
"protocol": "Tcp"
}
}
}
]
So in this case I need first two probes (FirstProbe and SecondProbe) to be explicitly defined but also I need more probes to be added based on someParam array values.

you just need to do this:
"variables": {
"probes-static": [
{
"name": "FirstProbe",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": 123,
"protocol": "Tcp"
}
},
{
"name": "SecondProbe",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": 456,
"protocol": "Tcp"
}
}
],
"copy": [
{
"name": "probes-loop",
"count": "[length(parameters('someParam'))]",
"input": {
"name": "[concat('OtherProbe', parameters('someParam')[copyindex('probes')])]",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": "[parameters('someParam')[copyindex('probes')]]",
"protocol": "Tcp"
}
}
}
],
"probes": "[concat(variables('probes-static'), variables('probes-loop'))]"
}
and then you can use variable('probes') as the result and assign it to the LB property
