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.
