Cold Call Cycle in Zoho CRM - Marking Tasks as Complete

Cold Call Cycle in Zoho CRM - Marking Tasks as Complete

Hey everyone, I'm trying to set up an SDR call system in our Zoho CRM. I've just created a blueprint where all our SDR call cycles will process through. We're currently using Phoneburner as our dialing integration. When I'm assigning leads I'd like to create a TASK that says to call the lead. Then our SDR will use phoneburner to call the lead - PB will create a closed call activity and update the lead status (via workflow rule). I would like when this lead status changes, for the original task to be marked as completed.

Can anyone help or has anyone done anything similar?
