I've create a custom field for initiative records that allows users to prioritize them on a scale from 1 to 10. I'd like to see that information reflected in a feature, so that the P.M can have both this initiative prioritization and the feature score to help them plan what will be in a given release.
This idea is not currently planned on our roadmap.
In the meantime, we would recommend using a list view or a pivot table to see these details together in a single view. For example, in the list view you could add columns to show the name and priority of the related initiative.
If you are on the Enterprise+ plan, you can add a custom worksheet to your feature record that references your initiative's custom field.
