Multiple influxURL in kapacitor chart

Let me try to explain what we are trying to do. Basically, we are using kapacitor to sync two DB.
We made a POC in EC2 without problems, we were able to register two different influxURL and sync the DB.

Now we are trying to move to kubernetes.
We would like to add multiple influxURL (https://github.com/influxdata/helm-charts/blob/master/charts/kapacitor/values.yaml#L66), but there is no mention of it in the documentation.

Is this possible with the chart out of the box (without modifications)?

As far as we were able to check, we will need to change the chart
https://github.com/influxdata/helm-charts/blob/master/charts/kapacitor/templates/deployment.yaml#L35
Add another `KAPACITOR_INFLUXDB_0_URLS_0` env variable (modifying the variable to add a new one).
```
- name: KAPACITOR_INFLUXDB_0_URLS_0
value: {{ .Values.influxURL }}
```

Anyone was able to do it without changing the chart?
We are trying to use kuztomization to avoid changing the chart everytime.

Start with charts/kapacitor/values.yaml around influxURL and charts/kapacitor/templates/deployment.yaml around the referenced environment variable. Check whether the chart supports multiple InfluxDB URLs without modification and how Kustomize can provide them. Done means confirming the supported configuration or documenting the required chart change.
