Before I pose my question, let me set a reference frame of what I'm getting at.
In Wing Chun/Ving Tsun they use Sticky Hands (Chi Sao) training. The purpose of this is to train your instinct and reactions. It does other things as well, but my attention is on training the reaction part.
In Tai Chi (Chuan) they use Push Hands. This is also to train reflexes/reactions/instinct/what have you.
In White Crane there is Entwined Hands (Pan Shou). Also this is trained for those same purposes.
Another form of practice is called Bridge Hands. This too is about training reactions.
What this all goes to say is that all these methods use partners. Does anyone know of a method similar to the aforementioned, but intended for practice by an individual? And no, I don't mean just forms/katas/chuans.
