I have an existing template with specific properties that are applied when new indexes are created.
For example, this exists
> ```
> {
> "final1-template": {
> "order": 0,
> "template": "final-*",
> "settings": {},
> "mappings": {
> "userjourney": {
> "properties": {
> "method": {
> "type": "text"
> },
> "page-uuid": {
> "type": "integer"
> }
> }
> }
> }
>
> ```
In the above, I want to add a new 'mapping'. Is this possible?

> },
> "page-uuid": {
> "type": "integer"
> }
> "newABC": {
> "type": "integer"

What have you tried? Did you get errors, what were they?
