I need to add a custom dropdown column in the Jira Structure view. The new column, titled "Health Check," should allow users to select one of three options from a dropdown menu: "On Track," "At Medium Risk," or "At High Risk." Additionally, it would be helpful if I could use markdown or similar formatting options so that the values appear with specific colors—for example, "On Track" should be displayed in green font. This will enhance clarity and visibility for users when assessing the status of issues.
