The Consultant can edit the programs for scalability and efficiency by creating a global program and coordinating campaigns to update the acquisition program to the latest program touched. This will allow the Consultant to streamline and optimize the process of updating the acquisition program for each lead, instead of having multiple flow steps in each campaign. The global program can use triggers and filters to capture leads from different sources and channels, and use tokens to dynamically update the acquisition program based on the latest program touched. This will also reduce the number of campaigns in the queue and improve the campaign performance.
