multiple leaders from a single label (i.e. "label clustering")

AKA Label Clustering.

Sometimes I have multiple features that I need to be distinct (for example, points that need to remain as multiple visible points as opposed to a clustered single point) but all of those points have exactly the same callout. Manual cleanup ensues, and often times I would like to have a single callout box, with multiple arrows pointing to the various similarly attributed features.

Here's a relatively poor example of what I mean (it would be much cleaner ideally):

Please add this feature ESRI, it has been over 13 years and there has been no solution offered. We have scores of users in our organisation who would collectively save a great deal of time if multiple lines were offered from the same label, whether that be graphic, annotation or both.
