Copy worksheet values when promoting an idea to become a feature

Please could worksheet fields work like regular custom fields and copy values when promoting an item from one type to another?

- When promoting from an idea to become a feature could worksheet values be copied?

This could work exactly the same as other custom fields types: when the key value for the custom field matches then values are transposed between items when promoted/demoted (https://support.aha.io/hc/en-us/articles/205249329-Carry-over-custom-field-values-from-ideas-to-features-master-features-and-initiatives).
