Delete the A/B testing option without deleting all the messages

We tested four different variations of the Runway Rogue brand, and after four weeks, we identified the winning variation. Now, to conclude the A/B test, I need to remove the A/B testing split and create again the messages accordingly.

It would be helpful to have an option to either select a winning path or have it converted into a standard path when all the variations are deleted.

Right now it feels really clunky to have to delete everything and do everything from 0.
