How to set BatchName with loggedIn UserName and populate in csv/xml file using WFR

Hello Experts,

Using the WFR 11.1.1.9.0 version and having the requirement as below.

Requirement:

How we can set the BatchName to loggedIn User Name in Verifer and populate the same value in csv and xml file.

Saw one document on support How To Customize Batch Names in WebCenter Forms Recognition (Doc ID 2210892.1), but unable to set the LoggedIn userName.

Example: in login Screen of Verifeir UserName value will be GroupName/UserNameDetail so need to set the BatchName as only UserNameDeatil. 

Please provide suggestion how I can achieve this functionality.

Thanks

Sanjeev
