Optional steps in funnel

In some instances, steps in a funnel are skipped.
For example, the step “Authentication” in the sales funnel is skipped if the user is already signed in.
This way, the user leaves the funnel even if they complete the following steps.

It would be helpful if steps could be marked as optional.

we have now released our third funnel type: Flexible funnels. flexible funnels require only the first and last steps to be completed. visitors can skip middle steps and still count as conversions
