1) “Mini” if/then statements that allow the branch to check for a condition, and if it doesn’t meet it then it goes back to the original branch. I don’t know the specific name for this type of thing in programming terminology but here’s an example. Let’s say that in a branch, I want to check whether or not a field is blank. If it is blank, I want to fill it with something. If it’s not, then it skips that action and continues onto the same branch. This isn’t possible currently and I have to copy the entire branch into the second option which is just silly and creates a huge visual mess. In other words, we can build conditional logic that can go back to the original branch if needed.
