Calendar Calls

Is there any way to filter calls that appear on the calendar to only show planned calls (or exclude held calls).
I only want to see current activity.
Means I can easily see calls / appointments etc for my staff that have not been done by the assigned date.
If you can not filter, can the colour change for planeed vs held calls?
Cheers

go to setting and make “Show Completed Meetings, Calls and Tasks:”-> No
