To add a unit, click on a section of the striped area (this area indicates scheduled working hours that have no assigned activity units).

A list of available activity units will be displayed.

The selected unit will appear in the schedule view.

To set an activity unit for more than one time unit (in this case, 15 minutes), you can hover the cursor over the edge of the unit and stretch it to extend (or shrink it to shorten),

select multiple “striped” time units before choosing an activity unit and then select the activity from the displayed list.

or, before selecting an activity unit, check the CHANGE HOURS OF A WORK TIME UNIT box, specify the start and end time, and confirm.

To remove an activity unit from the schedule view, right-click on it and select DELETE.

If you don’t want to delete the unit but only change it, select CHANGE instead of DELETE and choose the correct unit.
