ARM Template - Add Rule to multiple Network Security Groups

Hello,

I'm looking for a way to add one security rule to multiple Network Security Groups using an ARM Template. I tried to use the Take function, but the deployment fails. I would appreciate if someone could take a look and advise on that. I'm only working with ARM templates for about a week and I still have a lot to learn.

{"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#","contentVersion": "1.0.0.0","parameters": {"NSG-AppDMZ": {"defaultValue": "nsg-app-AppDmz-001","type": "string"
        },"NSG-AppDMZLotus": {"defaultValue": "nsg-app-AppDmzLotus-001","type": "string"
        },"numberOfProps": {"type": "int","maxValue": 13,"defaultValue": 13,"metadata": {"description": "Number of properties to deploy"
            }
        }
    },"variables": {"name": "allow-cmk-icmp-in-999","Properties":[
            {"description": "Test","protocol": "ICMP","sourcePortRange": "*","destinationPortRange": "*","sourceAddressPrefix": "192.168.11.50","destinationAddressPrefix": "*","access": "Allow","priority": 999,"direction": "Inbound","sourcePortRanges": [],"destinationPortRanges": [],"sourceAddressPrefixes": [],"destinationAddressPrefixes": []
            }
        ]
    },"resources": [
        {"type": "Microsoft.Network/networkSecurityGroups/securityRules","apiVersion": "2019-11-01","name": "[parameters('NSG-AppDMZ')]/[variables('name')]","location": "germanywestcentral","properties": "[take(variables('Properties'),parameters('numberOfProps'))]"
        },
        {"type": "Microsoft.Network/networkSecurityGroups/securityRules","apiVersion": "2019-11-01","name": "[parameters('NSG-AppDMZLotus')]/[variables('name')]","location": "germanywestcentral","properties": "[take(variables('Properties'),parameters('numberOfProps'))]"
        }
    ]
}

One problem I have is with the name when I'm trying to combine a name from the parameter and a name from the variable:

"name": "[parameters('NSG-NSG-AppDMZ')]/[variables('name']]",

At this point it fails at the validation

Deployment template language expression evaluation failed: 'Unable to parse language expression 'parameters('NSG-AppDMZ')]/[variables('name')': expected token 'EndOfData' and actual 'RightSquareBracket'.'. Please see https://aka.ms/arm-template-expressions for usage details. (Code: InvalidTemplate)

So I would appreciate if someone could point me to the proper way of doign this.

but even when I write the name explicitly:

"name": "nsg-app-AppDmz-001/allow-cmk-icmp-in-999",

I get a failed deployment.
