Issue Summary
Atlassian Goals should support custom metric types, where users can define a custom metric type and its values. For example: Happy / Neutral / Sad.

Steps to Reproduce

1)Go to Atlassian Goals and create a new Goal.

2)Add a metric to the Goal.

3)Try to set the metric type to a custom label or category (e.g., Low / Medium / High / Elite).

4)Notice that only numeric metric types are available — Number, Percentage, and Currency.

Expected Results
Users should be able to create a custom metric with an ordered list of labels (e.g., Low → Medium → High → Elite) and select one of those labels as the current value, with progress tracked accordingly.

Actual Results
Only numeric metric types (Number, Percentage, Currency) are supported.

Workaround
A partial workaround exists: users can map labels to numbers manually (e.g., Low = 1, Medium = 2, High = 3, Elite = 4) and use a numeric metric instead.
