Process mining using pafnow

Hi,

I'm using Paf now vizualization. Does anyone know if there is functionality to see the paths that starts with a spesific event?

I can filter on spesific events, but I don't see where can choose a spesific event as first event and see all the flows from there. 

I'm also looking for functionality to filter on duration between events. Like a path for users with maximun 1 day between events.
