without having the ability to see what contacts are on which campaign ( like in V1) it is hard to know which contacts need to be removed from the filtered list (bulk action) if the drip is getting assigned to hundreds of contacts. To know which contacts are on a campaign already makes for a faster process.
You can run a filter for all contacts that don't have a future autopilot tasks to see which clients do not have an autopilot task on them and then start the drip that way.
