No worries, and sorry for misunderstanding your issue.
Yes, it is possible, but looking at the link provided by you it seems that it is not implemented yet by the author.
If you know your way, consider forking, implementing and making a pull request back. If you don’t know how to do it you might consider to go for it and learn in the process, create an issue (feature request) or just wait.
…and I might just be wrong and misunderstanding the code or your questions.
