If it is still not clear after going through the instructions please post a new question with your specific question or some example and I should be able to look into it and provide you with a better solution.
I hope this has answered your query.
If this has answered your query then I would request you to please mark the question as resolved!! If not and you have a specific question related to this then please post it as a new question and we should be able to provide you the solution for it!!
