I've already made a siyum on a work. Can I make a full siyum a second time?
As a personal example, I completed learning all of Shas Mishnayot (with the Kehati commentary) for my thirteenth birthday. At the time, I made a siyum; with the Hadran Alach, the special Kaddish, the works.
I've been considering learning the whole thing again - to brush up on it and refresh my knowledge (I was fairly young when I learned it, after all). This would potentially include a second siyum, since I do plan on, well, finishing it a second time.
Can I make a complete siyum again, with the Kaddish for a siyum and everything else, for the same text that I've already made a siyum on?
