On feature card show number of related ideas

When we promote an idea to a feature, in the feature details we can see that in the "Related" tab. But when we see feature cards in the Feature board, there is no way today to add the ideas on the feature card. So unless we open each feature we cannot find out how many and which ideas it is related to. Just like requirements, if we can also add the "Ideas" field on the feature card, then it should show the number of ideas related on the feature card and when clicked on it can show all the ideas in the "Related" tab.
