The custom events funnel shows the total number of metric X, then the total number of metric Y. This is not useful for trying to view visitors who did one success event then proceeded to another success event.
I would like to see the total number of metric X, then the total number of metric Y that previously fired metric X in the visit. This would make the custom events funnel look like the pages fallout funnels, where it uses pathing to go from page to page.
Either pathing on events or funnel-layer segmentation would be sufficient.
