This might not be implemented, unsure if it’s a bug or a feature request now…
This can be worked around by creating a Server Action with a Redirect step to redirect to the intended destination. It’s a bit more complicated for non-technical people.
You would need to check the URL being accessed by inspecting a $_SERVER variable:
Extract everything after “teambuilding-firmenvents/” (the equivalent of :ort) and then use the extracted string to inject in the URL expression of the Redirect step
Sorry if this sounds a bit confusing, I lack the time to explain (and research the exact instructions), but I just wanted to nudge you in the right direction.
Might also be useful (look at the pathinfo variable):
