Adding a Resolution field to Plans / Advance roadmap

Problem definition:

In the Plans / Advance roadmap adding a field 'Resolution' is not possible.

Suggested Solution:

Allow adding the 'Resolution' field to the Plans / Advance roadmap.

Why is this important:

Providing a visual representation of the issues that need to be done or not.

Workaround:

Created a custom field (text field) to act as the resolution field.

Copy the value of the resolution field to the custom field via automation (or even workflow post function).

Add the custom field to the plan as a substitute.
