Reschedule Multiple/Mass Calls at Once

Reschedule Multiple/Mass Calls at Once

When we go into a Call record, we have the option to "Reschedule Call." How can we select multiple Calls at once from the Activities tab and Reschedule them?
The big use case for us: We have many leads that our reps are supposed to call on a daily basis. If the sales rep is sick or was not at work, we want to quickly select all 30 scheduled calls that they had on that day and reschedule them to another day. How can we achieve this?
