Swagger codegen - is it possible to change generated method parameter name?

I have a timezone offset header parameter in my contract:

parameters:
    - $ref: "#/components/parameters/timezoneOffset"


...


timezoneOffset:
      in: header
      name: X-Timezone-Offset
      required: true
      schema:
        type: integer
        format: int64

When generating code with swagger codegen, the parameter in method name is called xminusTimezoneMinusOffset.

@RequestHeader(value="X-Timezone-Offset", required=true) xminusTimezoneMinusOffset: kotlin.Long

That looks pretty bad and I would like it to be generated with let's say timezoneOffset variable name. Is it possible to do so?
