Within Teamwork, you can use the bulk edit
tasks feature to modify, complete, move, copy,
or delete multiple subtasks in a task at once.
Note: Only users with the project permission to edit all tasks can bulk edit subtasks on a project.
In the List area of your project, hover over
an existing parent task and click the three
dots to the left of the task name. In the
dropdown menu,
select the Bulk Edit
Subtasks option.

In the bulk edit modal, you can then select
an operation to perform on the subtasks:
- Modify
- Move
- Copy
- Complete
- Delete

Modify
When you select the modify option, you will
see the different task properties you can
update. Use the checkboxes to the left of each property to select which properties should be updated. You can then choose the new properties for each highlighted option.
Click Update All Subtasks to apply the changes.
Note: The bulk modify subtasks
feature only applies to the first level of
subtasks.

- Reassign - choose the individuals,
teams, or companies to reassign to the
subtasks.
- Start date - choose a new start
date.
- Due date - set a new due
date.
- Progress - choose the new
percentage of progress.
- Estimated tIme - add the estimated
time in hours and minutes.
- Priority - choose a new
priority.
- Set column - choose a board
column for the subtasks.
- Change creator - choose the
person marked as the creator of the
subtasks
- Tags - add or remove tags on all
selected subtasks.
- Task Changes Followers - adjust who
is following changes to the selected
subtasks.
- Comment Followers - adjust who is
following comments added to the
subtasks.
When updating the assignee and
follower options, you can choose
individuals, teams, and
companies.
For the task changes and comment
followers options, you can add to
the existing followers, remove
some existing followers, or use
the Remove
All option in the
dropdown.

At the bottom of the modal, you can choose to
apply the new settings to all of the tasks, or
just those with particular start and due dates
or assignees.

Move
When choosing the move option, you can select
a destination project and task list. If you
don't want to use an existing task list, you
can create a new list from within the
modal.

Copy
As with moving subtasks, the copy option
allows you to select a destination project and
task list. You can also create a new list from
within the modal as your destination
list.

Complete
When you choose Complete from the operation
dropdown, you can then click the Complete
Subtasks button in the modal.

Delete
Similarly to the complete action, when you
choose to delete, you need to click the Delete Subtasks button in the
bottom right of the modal.
