In Ableton, you can set follow actions to tell clips to do something on a timed basis. The time can be immediate or random, but it is automated. This is more efficient than doing the follow actions manually. Go to clip view, type "L". This launches the settings which gives the space of time in which the follow action happens. You can set more than one follow action. You can determine when and how often the action will take place. You can determine when the clips occur automatically. The clips can be set to trigger each other by stating in the launch dialog that B follows C. Play the clips to confirm.
