Ability to Promote an Idea to a workspace

In the scenario where you have a central Ideas portal to manage demand which may result in the building of a new product/asset, it would be hugely beneficial to be able to promote an idea to a workspace (so that a new workspace is created from the idea). At the moment, the workaround is to manually create a workspace and promote the idea as an initiative in the new workspace to ensure there is a link back to the idea.
