Creating a sequential funnel that includes a step with multiple events is not directly supported as funnel metrics are designed to be linear, with each step corresponding to a single event. However, you can gain similar insights by utilizing Ratio Metrics.
Ratio Metrics allow you to define a metric using other metrics as the numerator and denominator. This means you can create a metric that combines the counts of multiple events, which can provide an analogous understanding to having two events count as the same step in a funnel metric.
To implement this, you would define a new Ratio Metric where the numerator is the sum of the events you wish to combine, and the denominator is the preceding event in the funnel. This approach allows for flexibility in analyzing user behavior across multiple events without altering the linear structure of funnel metrics.
