In GorillaDesk you have the ability to batch reassign jobs with a few clicks of a button. First, click on the options button in the upper right corner of your Calendar view. You'll then have the ability to select the Schedule you would like to reassign, the date range for those jobs, and who you would like to assign them to. You will also have the option to 'reassign this job only' or 'reassign all recurring jobs'. 

Once you have selected the jobs you would like to reassign, 'Accept Changes' so your changes will now be reflected on the appropriate schedule.
