Why can't 'Section Callouts' be edited and applied globally in the same file?

Question

I discovered that same 'Section Callouts' have to be laboriously edited in the model separately from every sheet in the same file, this doesn't make sense! Worst if you reload the callout after editing (by clicking 'show callout' button'), it revert back to the default labels, you lose the amendments and all the hard work for nothing, that is horrible! 
 It seems these updates are getting nowhere or am I missing something?

Ben, 
 Ben Adarqua said: The callout was edited directly as expected, but not used with 'dynamic' view instead with 'cache' on Visible Edges. 
 I was referring to a dynamic view workflow, in which callout represents 2d drawings generated from 3d models (both dynamic and cached). Sometimes, callout(s) are used in 2D drawings which does not involve 3d models. In such workflows, it should be ok to edit them manually. 
 Ben Adarqua said: In this case they were not linked that is why the callout was not updated automatically! 
 The link will be automatically established, if the drawing is inserted as a reference in the sheet. 
 Ben Adarqua said: Of course. Section EE was generated by the 'Section Callout' as drawing model which was attached to copy of a sheet model already containing project info. and updated to suit. 
 Attaching a short video clip to explain the process. 
 For the convenience of explaining the link between callout, drawing title and sheet number: 
 1. I have manually created the sheet model and attached the drawing to the sheet as a reference. 
 2. I have illustrated the workflow in a multi model view and created the drawings and sheets within the same design file. 
 
 Happy to assist.
