How to add the file name to objects created by Smooks splitter?

Issue

We are using Smooks to process a csv file where each line maps to a simple object model. In addition to the input data, we need to obtain and append the following to the object model
- filename
- line number
- line length

We are using the following smooks configuration to parse the csv file:

    <csv:reader fields="firstName,lastName,gender,age,country">
        <csv:singleBinding  beanId="customerList" class="example.Customer"/>
    </csv:reader>
