MACD Filter afl

Hi, I am trying to scan for MACD crossover in amibroker. I would like to go with All quotes and All Symbols. If i go with this and scan/explore, it displays the results with lot of data say for the same symbol so many positive and negative crossovers. But what I want is it should display only the latest crossover. say for Scrip RELIANCE, it might have had so many positive crossover and so many negative crossovers but it should display only one RELIANCE in the result along with type of its latest crossover and date and time on when it happened.

Can anyone please help me on this. Thank you
