funnel widget and Business Journey

[jaganathan.ellappan]

Hi All

I have already learned to do Funnel and Business Journey. My application is created using NodeJS.

My question,

1. is it possible that I can create a funnel using only the business transaction name as a unique ID without any other unique ID. If yes then kindly share me steps or ideas. My output should show count each business transaction and Abandoners. If no, is there any other possible way?

2. Are Business Journeys possible with Business transactions? If yes, let me know how to work out those. 

Example

I tried with each business transaction on each milestone and the primary key would be the same business transaction.

I see the output only counts of the transaction on each business transaction and I don't see any timely action which shows 0 ms on transit between milestone.
