Hi Enis, AFAIK, not in Vegas alone. Among the many functions of Vegasaur is one that splits events at specified frame intervals. You can get a free trial (http://vegasaur.com/download), probably won't take much to convince you to buy it once you've tried it.
At first I thought it was a lot of money since I already had Production Assistant Pro 2, Timeline tools, and FAST Apps. With the move to Magix, only Vegasaur and a couple FAST Apps work. Now I have come to appreciate that Vegasaur covered all my needs, especially for slide shows.
