No, you can't. Any participant who attends training for the first time must make payment depending on the place of training. If the participant wants to attend training repeatedly, he can do it for free. For this purpose he must bring with him a paying guest attending the training for the first time and correspondingly, paying for his participation. You can register your second participation filling in your name in the column "Participant's Name (Repeater)" in Humans Being More Register Form, filled in by the paying guest, attending the training for the first time.
