I’m going to create module which affect core functionality. This is flow module. I have predefined flows (customer journey steps). And on each step (page) I want to have next button to follow next step. For ex. On Campaign page i want to include NEXT button and after submit follow next page.  
  
What is the best way to do that? I want use core updates but in case I’ll modify core bundles files my changes would be overwritten.  
  
  
  
Thanks in advance!
