I previously was able to install a decision diamond while building a campaign. but I can’t find out how to do it anymore
the decision diamond shows up automatically when you connect two sequences to a previous item (goal or sequence)
If what you want is simply some conditionals placed before a specific sequence, you’ll need to create a dummy sequence with nothing in it, then drag the arrows to the dummy and the real sequences. The decision diamond appears automatically and then you can put the conditionals on the real sequence and just let everyone fall into the dummy sequence. I guess the theory here is that contacts in campaigns need to be able to flow somewhere, and the decision diamond both allows conditionals and forces you to decide what happens if a contact meets none of the conditions (it’s at the very bottom of the decision diamond screen).
