Ok, I see.
For me the setting up the permalinks is too limited. Another thing is, that I want to have
domain.com/f/funnelname/buy
domain.com/f/anotherfunnel/buy
Both checkouts in each funnel with /buy.
One it possible the other not because it needs to be unique.
When I have 50 funnels with another landing and other setups, I need to add 50 checkouts with different names… Thats incredible and not maintainable – also not trackable.
What can I do?
