My suggestion would be to learn to play it straight first. Get everything else right. If you really want to "chunk", learn how to do it separately. But remember, it is a very, very overdone technique. It can sound silly if it is not done well and I'm afraid it is too often done badly. Many people use it too much too.
In the hands of a really brilliant player, like Aldrine for instance, it can sound magical. Done precisely it can enhance your playing.
Many players never use this technique at all. Others only use it when the piece calls for it. Learn how to do it well, but don't be tempted to use it in every song.
