Managing hours for different event types: phone calls and meetings

Hello Friends.

Previously….. I had a variable within Event Types;

Meeting types had a certain set of hours while Phone Calls had a different set of hours.

I would like to avoid having to go into each Event Type to make the changes as that would be incredibly tedious as I have different times for different types of meetings such as in house appointments, remote appointments, and phone calls.

All my Event Types now display the same Meeting hours.

I cannot find the Phone Hours anywhere or any info on how to redo this setting.

Any advice?

Thanks in advance.
