Cloudformation template(JSON) for security group with 50 CIDR IPs (Ingress)

I am creating Cloud formation template for security group with ingress rule of over 50 CIDR IPs.
In Parameters, I used Commadelimited list for Multiple CIDR IPs.
Instead of creating seperate values in SecurityGroupIngress for each CIDR IP, Is it possible to include multiple CidrIps in single code.

                    {
                        "IpProtocol" : "tcp",
                        "CidrIp" : "54.183.255.128/26",
                        "FromPort" : "443",
                        "ToPort" : "443"
                    },
                    {
                        "IpProtocol" : "tcp",
                        "CidrIp" : "54.228.16.0/26", 
                        "FromPort" : "443",
                        "ToPort" : "443"
                    },
                    {
                        "IpProtocol" : "tcp",
                        "CidrIp" :  "54.232.40.64/26", 
                        "FromPort" : "443",
                        "ToPort" : "443"
                    },
                    {
                        "IpProtocol" : "tcp",
                        "CidrIp" : "54.241.32.64/26", 
                        "FromPort" : "443",
                        "ToPort" : "443"
                    },

Template I want to use like below. But here I can able to get only 1 position CIDR IPs.

>Solution :

Sadly its not possible. One security group (SG) rule applies to only one CIDR range.

There is a limit of 60 rules in a SG, which you can request to be increased.

Although a single SG rule can refer to single CIDR, you can create CloudFormation macro or custom resource to automatically create all these rules for you.
