Leader arrows/text for rendered assets

Would it be possible to have a ‘leader’ feature to help with presenting designs? When D5 releases new vegetation assets you do a great video showcasing them with leaders telling viewers what they are, so I was wondering whether this could be a feature of D5 rather than having to add them in video editing software?

This could look really good when combined with phasing animations, I’d use it to drop vegetation into my garden designs with a 3 second leader identifying each variety as the camera passes. They could also be used in static image renders to help create planting plans.
