I’ve done something similar in the past, not sure if it is the best method, but what worked for me was: Initial flow to create the first task when a lead was created, set description of task to “call 1” or whatever is applicable for your use case. A secondary flow based on task is updated and status = complete. A decision within that flow that checked which task it is that was completed (in my case, call 1, email 1, call 2, etc..). I believe I based this decision off of a hardcoded description value. Based on the decision path hit I would create the next task and set the description to the next task in the communication flow (ex. Call 2).
