## Create multi tasks

To add several tasks in one go, open the task configurator:

![Multitack configurator](/images/multitask_configurator.png)

And specify the following parameters:

1. In the **Name** field, enter the name of the new task:

   - Enter the name of the task. If the name includes more than one word, use the underscore: `Word1_word2_word3`
   - (Optional) `{{index}}` adds an index to the file in the set (starting from 0).
   - (Optional) `{{file_name}}` adds the file's name to the task's name.
     > **Note:** use hyphen between three parameters: `Word1_word2_word3-{{index}}-{{file_name}}`

2. (Optional) From the **Projects** drop-down, select a project for the tasks.
   <br>Leave this field empty if you do not want to assign tasks to any project.

   > <br>If the tasks have been assigned to a project, the project's labels will be applied to the tasks.

3. On the **Constructor** tab, click **Add label**.
4. In the **Label name** field, enter the name of the label.
5. (Optional) Select the color for the label.
6. (Optional) Click [**Add an attribute**](/docs/manual/basics/create_an_annotation_task/#add-an-attribute)
   and set up its properties.
7. Click [**Select files**](/docs/manual/basics/create_an_annotation_task/#select-files)
   to upload files for annotation.
   > **Note:** You cannot upload multiple tasks from the cloud storage.

   only the total number of selected files will be displayed:
