Request for Custom Funnel Visualization Options in Analytics

hi all, is there a visualization option to show a funnel that has multiple options, like a Sankey diagram, but where i determine each level. In the Flows report it gives me all possible events, where i want to pick only the key events. for example: A: app install -> B: login attempt -> C1: login success -> C2: login fail error type 1 -> C3: login fail error type 2
