Hi, I have a watcher that takes people's data as input. If someone is below 21 yo it triggers the watcher and fires an index action. However I now need to add an additional field to the payload, which is "watchername" and just assign some value to it. All watchers will send data to the same index and I need it to differenciate the watchers later in the index, that's why I need the watchers name. I tried some things in the transform: `ctx.payload.hits.hits.put("watchername", "name")`,  
and also

` return [ctx.payload.hits.hits, "watchername": "name"]`

but nothing works. It just could be a hardcoded value that we will set up, it doesn't have to really take the watchers name.  
Any ideas? Thanks in advance

I assume that you are using the [index action](https://www.elastic.co/guide/en/elasticsearch/reference/current/actions-index.html) of Watcher, with a transform script. That link has an example transform script that is able to modify _every document_ that the watcher is indexing. In the example watcher script from those docs, you could do `"watcherName": "name"` into the \_doc instead of changing severity.
