"Bulk Reassign PMs" allows you reassign multiple PMs to a different Team or User.

After clicking "Bulk Reassign PMs" a window appears with all your PM Templates. Once selecting the PMs you want to reassign, click "Select".

Then you can choose who you want the Tasks assigned to. Once you are finished, click "Select".

"Bulk Change PMs' Asset" is used to change which Assets Tasks are assigned to. Once clicking "Bulk Change PMs" Asset" will pull up all available tasks.

Once you select our tasks, click "Select."

After, you will be prompted to choose your Asset.
