Allow custom fields to be clickable on a roadmap

What is the challenge?

Today, custom fields do not pull up the epic records on a roadmap unless it's a stock field. Ex: Epic name is clickable from the data above the bar on a roadmap. If I use a custom field called "External name" that field is not clickable.

What is the impact?

We have to add additional fields to our data above the bar on a roadmap. Ex: Epic ref# so the epic is able to be drilled down in.

Describe your idea

Allow custom fields to pull up the epic from data above the bars on roadmap items.
