Hello, can i mutate convert multiple fields to a data type at once, without putting it one by one? something like:

```auto
filter{
  mutate{
    convert(["someField1","someField2","someField3"] => "integer")
  }
}

```

I have a large number of column and it's taking too long to define it one by one. Thanks.

No, that syntax is not supported.
