helm to create single configmap with different labels - kubernetes-helm

Question

can anyone help me creating configmaps in helm with different labels.
I have 6 configmaps each have their own labels which will be used by pods. I would like to have the same labels in helm as well. Is it possible in Helm?
These are my values for configmap. I want to render these values and create separate configmap.
values.yaml/
configmaptestingforhelm:
configmapref1:
confname: serviceaccount-config
key: serviceaccount.test.path
value: /root/test_key.json
configmapref2:
confname: host-credentials-config
key: secret.credentials.host.path
value: /root/host_key.json
I am trying to create separate configmap for each configmappref* as below
configmap1
apiVersion: v1
kind: ConfigMap
{{- range $value := .Values.configmap.configmapref1 }}
metadata:
name: {{ $value.confname }}
data:
{{ $value.key }} : {{ $value.value }}
{{- end}}
configmap2
apiVersion: v1
kind: ConfigMap
{{- range $value := .Values.configmap.configmapref2 }}
metadata:
name: {{ $value.confname }}
data:
{{ $value.key }} : {{ $value.value }}
{{- end}}
My expected output is as below ,but I am not getting the desired output
apiVersion: v1
data:
secret.credentials.host.path: /root/host_key.json
kind: ConfigMap
metadata:
name: host-credentials-config
apiVersion: v1
data:
serviceaccount.test.path: /root/test_key.json
kind: ConfigMap
metadata:
name: serviceaccount-config
