You can create custom fields to appear in your Bar details to help standardize roadmaps across your account.
Admins can create a custom field from their account settings page. Today custom fields are open text fields that you can apply a custom label to:
Once configured, you can click on a Bar on your roadmap to enter information into the custom field.
You can also choose to view your custom field as a column in your Roadmap's table layout.
By default, custom fields will not be selected to display but you can turn them on by clicking on the gear on the right hand side of your table layout and checking the box next to the field title.
You can create a single custom text field today. This is at the account level, and once saved will apply for any roadmaps on your account.
