You can define custom fields with Gtmhub that go with tasks. By default, Gtmhub will store info from the built-in fields. However, you can easily add more fields to suit your needs.

Idea for task custom field
Task custom field
Let’s say you want to add a Priority custom field for your tasks. You can create a custom field for tasks with this information:
Name: taskpriority
Programmatic name of the field. This field has several requirements: must be unique, must be lowercase, can be letters only, has to be between 4 and 12 characters
UI Label: Priority
This is the name of the field that will be displayed in the user interface. There're no requirements here
Description: Identify which priority level this work takes
A hint to users on how to use this field
UI Selector: Drop-down menu
Type of the field depends on the type of information you want to store in this field
Target type: Task
Once you've created your Priority custom field, you can use it when you're working with your tasks.
