I am trying to match multiple fields to a single value then mutate the field if necessary in a single if statement instead of having multiple different If statements

For example:

if [1] or [2] or [3] = null {

```
mutate {
             gsub => ['Field(s) That Matched, "null", "0"]
}

```

}

would this be possible?
