Field for linking external mockup/prototype/data on each Feature in the Roadmap in UV Validation
Description, image, and video are great to showcase about specific features but having a custom URL link option for each feature would enable lots of scenarios including links to detailed designs, mockups, figma prototypes or even extended feedback forms.
That would be just another field to populate in Edit mode and for end users could be just another "Learn more" section like the "Ideas related to this feature" shows below description.

Mocked up something to show how this would work for end users
