Differentiation on Ideas Portal of Idea Promotion Work Item Type

Many of our Ideas entered from the ideas portal become Features in our backlog, however there are also ideas that become Epics/Master Features. When an idea is promoted a feature or an epic, the idea status changes to "Likely to Implement". It would be great to somehow be able to differentiate on the Ideas portal for our stakeholders to know that this idea may take longer to deliver because it is very large, therefore an epic, as opposed to a smaller feature.

This could be achieved by adding a field onto the idea showing the work type, or perhaps by having different workflows (statuses) shown on the Ideas Portal for the different work item types.
